The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This paper proposes FORLAPS, a five-step framework that uses offline reinforcement learning with a state-dependent reward function to reorder activities in business processes, and claims it cuts resource time by 31% and total process span by 23% on a real event log from a Canadian energy regulator. The key idea is to penalize a disapproved activity more heavily the later in the trace it occurs, so the learned policy front-loads risky tasks and short-circuits cascading failures. To compensate for scarce historical data, the paper adds process-aware data augmentation that preserves business rules, enabling offline fine-tuning without online interaction. If the reported savings hold, the framework provides a practical decision-support tool for prescriptive process monitoring that goes beyond prediction to recommend optimal next steps.

What carries the argument

The central object is the state-dependent reward-shaping function $R(s_t,a_t)=-r\,|s_t|\,\mathbb{I}(s_t,a_t)$, which returns a penalty proportional to the number of activities already executed when the chosen activity leads to a KPI violation. This length-aware penalty is what makes the Q-learning agent prefer to surface risky activities early. The second load-bearing component is the process-aware data augmentation: timestamps are shifted by up to 10% of inter-activity time, non-critical activities are selectively removed from completed groups, and the synthetic traces are filtered against business-rule constraints, allowing the pre-trained Q-function to be fine-tuned offline as if exploration had continued.

What would settle it

Replay the learned policy on the energy-regulator event log while keeping each activity's real per-activity duration and order-dependent approval probabilities; if reordered traces do not reduce resource time by 31% and process span by 23% (or if they increase either), the central claim collapses.

Watch

Extended reading notes

Core claim

On its own terms, the paper establishes that a Q-learning agent over process states, trained with a length-aware reward $R(s_t,a_t)=-r\,|s_t|\,\mathbb{I}(s_t,a_t)$ and fine-tuned on augmented traces, learns to recommend activity orders that outperform both a multi-task LSTM next-action recommender and a permutation-feature-importance baseline. When 15,000 test-set traces are replayed with the learned policy, the paper reports 31% savings in resource time spent and a 23% reduction in process time span, with an average 2.66 fewer days of resource time and 9.69 fewer days per case compared with a baseline of 8.52 days per activity and 40.56 days per case. The framework also yields a ranked set of best next activities rather than a single action, and its robustness is assessed with Damerau–Levenshtein distance across nine public event logs from healthcare, finance, permits, and operations.

Load-bearing premise

The savings numbers assume that replaying 15,000 traces with the learned policy is a valid counterfactual: activities can be reordered freely, their durations and approval outcomes are order-independent, and an early disapproval allows later activities to be skipped.

Editorial extensions

If this is right

  • Applied to new applications at the energy regulator, the learned policy could reduce resource time spent on reviews by roughly a third and total approval time by about a quarter, if the replay assumptions hold.
  • Because fine-tuning is fully offline, the same recipe transfers to domains where online interaction is expensive, such as healthcare treatment pathways and permit processing.
  • The policy does not prescribe one rigid sequence; it outputs a ranked list of next-best activities, so decision-makers can choose among near-optimal actions under operational constraints.
  • The Damerau–Levenshtein validation indicates the framework both reproduces traces that lead to desired outcomes and avoids traces that lead to undesired ones, across different prefix lengths.
  • Performance is strongest when the event log has dense state coverage relative to its number of activities; sparse logs such as BPIC_2015 are an explicit boundary of the method.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • The 31% and 23% figures depend on a replay counterfactual that the paper never fully specifies; if activity durations or approval outcomes are order-dependent in the real process, the realized savings could differ even if the Q-learning converged correctly.
  • The same reward-shaping principle — penalizing late failure linearly in trace length — could be ported to other continuous KPIs such as cost or defect counts, as long as the state encodes those dimensions.
  • A natural next test is a real A/B trial where the policy's reorderings are applied to a random subset of cases; if early disapproval does not reliably cancel downstream work, the resource-time gain shrinks.
  • The analogy to fast-fail in manufacturing suggests the framework may transfer well beyond business process mining, to any sequential task where late-stage failure is disproportionately expensive.

Referee Report

4 major / 6 minor

Summary. The paper proposes FORLAPS, a five-step prescriptive process monitoring framework that combines offline reinforcement learning with a state-dependent (length-aware) reward shaping mechanism and a process-aware data augmentation technique. The authors apply the framework to a real-life event log from a Canadian energy regulator and report 31% savings in resource time spent and 23% reduction in process time span, comparing favorably against LSTM and Permutation Feature Importance baselines. They also report improved Q-value convergence on nine public datasets and validate the recommended sequences using Damerau-Levenshtein distance at both trace and prefix levels. The central claim is that FORLAPS reliably identifies optimal execution paths and provides context-sensitive next-activity recommendations without online environment interaction.

Significance. If the empirical claims were substantiated, the paper would offer a practical, data-driven approach to prescriptive process monitoring in data-scarce, high-stakes settings, and the integration of length-aware reward shaping with process-aware augmentation is a sensible direction. The authors provide source code on GitHub and evaluate on a diverse set of datasets (Sepsis, BPIC 2015/2017/2019, Traffic Fines), which is a strength. However, the headline results rest on an unspecified replay simulator, and the Q-value improvements are partly circular because the augmentation is described as selectively increasing Q-values. As written, the contribution is not fully established, and the evaluation protocol needs substantial clarification before the claims can be accepted.

major comments (4)
  1. [Section 3, Table 3] The replay simulation that produces the 31% resource-time and 23% time-span savings is not defined. The text says "we replayed 15,000 traces from the test set of event logs using the learned optimal policy," but no transition function, duration model, activity outcome (approval/disapproval) model, or cancellation/revision semantics are specified. The process in Section 2.1 is described as having up to 10 revisions and partially parallel activities, and Section 3 itself concedes that sequential reordering may add delays. Without an explicit simulator, the KPI computations are not reproducible and the comparison against LSTM and PFI baselines is uninterpretable. This is the core empirical claim, so the paper must provide a precise replay model and re-run the evaluation.
  2. [Sections 2.3, 3, and 4.2] Reporting Q-value increases as performance improvements is circular. The abstract and Section 2.3 state that the augmentation technique "selectively increases the average estimated Q-values in sampled batches," and Section 3 then reports a 44% Q-value improvement during fine-tuning, while Section 4.2 reports "outperformed the Offline RL agent by 28 percentage points on the Sepsis dataset and 33 percentage points on the BPIC_2017 dataset" as superiority. If the augmentation is intentionally designed to raise Q-values, higher Q-values are not independent evidence of a better policy. The paper should use externally defined metrics (e.g., expected return under a fixed simulator, success rate, or downstream KPIs) to compare policies, and should either drop the Q-value-based superiority claims or present them only as convergence diagnostics.
  3. [Section 2.3, Eq. (4)] Equation (4) is malformed: it uses the subset symbol "⊆" for trace membership, mixes universal and existential quantifiers with an unclear implication scope, and does not define the validity predicate V(σ', b) that it claims to formalize. As written, the equation cannot be implemented or checked, yet it is the formal basis for the "process semantic check" that the augmentation is said to satisfy. This needs to be rewritten as a precise logical condition over traces, business rules, and the augmented log.
  4. [Section 5 vs. Section 2.3] The paper contradicts itself on whether fine-tuning is offline or online. Section 2.3 says "we enhance policy learning through a fine-tuning phase conducted entirely in the offline setting" and the method is "fully compliant with an offline RL paradigm," but the Conclusion (Section 5) describes FORLAPS as "a hybrid technique that combines offline pre-training with online fine-tuning." This is not a minor wording issue: it changes the nature of the method and its claimed applicability to settings where online interaction is expensive or infeasible. The authors must unambiguously state the operating mode and ensure all sections are consistent.
minor comments (6)
  1. [Section 3, Table 3] The column header "Opt%" is never defined, and the table reports a "96% confidence interval," which is unusual; please define the statistic and justify the confidence level.
  2. [Section 1, Introduction] The introductory paragraph contains a duplicated discussion of manufacturing environments: "Manufacturing environments face similar challenges..." is followed by "Similarly, manufacturing environments rely on well-ordered production activities..." Please remove the redundancy.
  3. [Section 4.1] The phrase "80'%" contains a stray apostrophe and should be "80%."
  4. [Section 4.3] The sentence "BPIC_2019 showed that LSTMs lightly outperformed offline RL" likely means "slightly outperformed"; please correct the typo.
  5. [Section 2.3, Eq. (5)] Equation (5) is not a correct optimal-policy equation: it mixes an argmax over actions with an argmax over policies and omits the expectation over transitions. Please rewrite it using standard notation.
  6. [Section 2.2, Eq. (2) and Algorithm 1] The reward function is written as $-r|s_t|\mathcal{I}(s_t,a_t)$ in Eq. (2) but as $reward \leftarrow -r \cdot |s_t| \cdot \mathcal{I}(s_t,a_t)$ in Algorithm 1; please align the notation and clarify whether the indicator function depends on both state and action or on the outcome only.

Circularity Check

1 steps flagged · score 6.0 of 10

Augmentation success is reported with the same Q-values the augmentation is designed to increase, making the 44% and 19-33 percentage-point 'performance' gains circular; the KPI comparison is independent but underspecified.

  1. self definitional [Abstract; Section 2.3 (Process data augmentation); Section 3 (fine-tuning results); Section 4.2 (Results and discussion)]
    "To further enhance learning, we introduce an innovative process-aware data augmentation technique that selectively increases the average estimated Q-values in sampled batches... The observed improvement in policy quality corresponds to higher estimated Q-values, providing empirical evidence that the model’s value estimation reliably converges as training proceeds... Overall, the fine-tuning process yields a 44% improvement in performance... [Section 4.2:] it outperformed the Offline RL agent by 28 percentage points on the Sepsis dataset and 33 percentage points on the BPIC_2017 dataset."

    The augmentation is introduced as a procedure that selectively increases average estimated Q-values, and the same estimated Q-values are then used as the success metric: Figure 2 tracks mean Q-values, Section 3 reports a 44% 'improvement in performance' from fine-tuning, and Section 4.2 reports 19-33 percentage-point gains from the Q-value curves in Figures 5-6. Because the manipulated quantity is also the reported outcome, these gains are expected by construction and are not independent evidence of better process prescriptions. The Damerau-Levenshtein comparisons are a separate, non-circular check, but the headline augmentation-related performance numbers reduce to the augmentation's own objective.

full rationale

The paper's strongest formal circularity is in the evaluation of the augmentation/fine-tuning component: the augmentation's stated purpose is to selectively increase average estimated Q-values, and the paper's 'performance' gains (44%, 19-33 percentage points) are measured as increases in those same Q-values. This is a by-construction reduction and warrants a score of 6. The 31%/23% KPI savings on the energy-regulator case study are not formally circular, but they depend on an unspecified replay/simulation of reordered traces; I treat that as reproducibility/correctness risk, not circularity. The Damerau-Levenshtein validation against LSTM and offline-RL baselines is an external metric and gives some independent support to the general claim of improved sequence recommendation. The self-citations (Abbasi et al. 2024; Khadivi et al. 2023/2024) are background references and are not load-bearing, so they do not increase the score. Overall, the central contribution is not wholly defined by its inputs, but a prominent set of performance claims does reduce to the Q-value objective.

Assumptions & free parameters 6 free parameters · 6 assumptions · 0 invented entities

The framework introduces no new physical or ontological entities; its components are algorithmic (reward shaping, augmentation, fine-tuning). The central claim rests mainly on fitted parameters (r, alpha, gamma, augmentation scales) and on domain assumptions about MDP modeling, replay validity, and semantic validity of augmented traces.

free parameters (6)
  • base reward penalty r = not reported
    Constant in Eq 2; scales all penalties and affects the learned policy; chosen by hand or hyperparameter search.
  • learning rate alpha = not reported
    Q-learning step size; tuned via 'comprehensive hyperparameter search' in Section 3.
  • discount factor gamma = not reported
    Q-learning discount; tuned via hyperparameter search in Section 3.
  • timestamp noise epsilon = uniform[-0.1, 0.1]
    Augmentation noise range in Eq 3, chosen by hand without stated justification.
  • augmentation scale = 100K and 200K timesteps
    Number of augmented timesteps used in fine-tuning; chosen without stated criterion in Section 3.
  • activity removal fraction = 5% of completed groups
    Augmentation parameter for removing groups/activities in Section 2.3; chosen by hand.
assumptions (6)
  • domain assumption Event log traces can be modeled as an MDP with state = executed activity sequence and deterministic transitions.
    Section 2.2 defines states as sequences of actions and ignores parallel execution and stochastic outcomes; activity statuses are treated as fixed.
  • domain assumption The historical event log is a valid behavior policy for offline Q-learning with no unobserved confounding or selection bias.
    Q-learning updates use only observed state-action tuples; no coverage or distribution-shift correction beyond augmentation is provided.
  • ad hoc to paper Reordering activities according to the learned policy does not change activity outcomes or durations; savings arise because early disapproval can skip later work.
    KPI definitions in Section 3 compare original traces with reordered versions; this assumption is not tested or modeled explicitly.
  • ad hoc to paper The length-aware penalty -r|s_t| I(violation) aligns with true process cost and preserves the intended optimal policy.
    Eq 2 is presented as reward shaping, but no potential-based shaping argument is given, so the modified MDP's optimal policy is not justified.
  • ad hoc to paper Augmented traces generated by timestamp noise, duplication, and removal satisfy business constraints, as per Eq 4.
    Eq 4 is not well-formed, so compliance is asserted rather than demonstrated.
  • standard math Q-learning with tabular value iteration converges on these event logs.
    Bellman updates in Eq 1 are standard, but offline data coverage and convergence are not analyzed.

The application of artificial intelligence and machine learning in business process management has advanced significantly, however, the full potential of these technologies remains largely unexplored, primarily due to challenges related to data quality and availability. We present a novel framework called Fine-Tuned Offline Reinforcement Learning Augmented Process Sequence Optimization (FORLAPS), which aims to identify optimal execution paths in business processes by leveraging reinforcement learning enhanced with a state-dependent reward shaping mechanism, thereby enabling context-sensitive prescriptions. Additionally, to compare FORLAPS with the existing models (Permutation Feature Importance and multi-task Long Short Term Memory model), we experimented to evaluate its effectiveness in terms of resource savings and process time reduction. The experimental results on real-life event logs validate that FORLAPS achieves 31% savings in resource time spent and a 23% reduction in process time span. To further enhance learning, we introduce an innovative process-aware data augmentation technique that selectively increases the average estimated Q-values in sampled batches, enabling automatic fine-tuning of the reinforcement learning model. Robustness was assessed through both prefix-level and trace-level evaluations, using the Damerau-Levenshtein distance as the primary metric. Finally, the model's adaptability across industries was further validated through diverse case studies, including healthcare treatment pathways, financial services workflows, permit applications from regulatory bodies, and operations management. In each domain, the proposed model demonstrated exceptional performance, outperforming existing state-of-the-art approaches in prescriptive decision-making, demonstrating its capability to prescribe optimal next steps and predict the best next activities within a process trace.
