Application of Adaptive Neuro-Fuzzy Inference Systems in Development of Just-In-Time Pull Product Control Policies

Abstract: Just-in-Time manufacturing processes minimize inventory levels through effective control strategies. Pull Production Control Policies (PPCPs) authorize when and where to process, minimizing inventory levels while maximizing order fulfilment. This study investigates the development of PPCPs, by designing authorization mechanisms, measuring their performance, and evaluating alternative policies.

To do so, the research applied analytical, simulation, and intelligent computing methods, and each is examined through implementation in an actual industrial case. Horizontally Integrated Pull Control Policies (HIPCPs), combining the classic Kanban and ConWIP strategies, are proposed here as PPCP alternatives. Discrete event computer simulation techniques are applied to measure the performance of alternatives in a multi-stage and multi-layer manufacturing and assembly system with uncertain parameters. Fuzzy methods are applied to address the uncertainty. The proposed HIPCPs alternatives, together with Kanban and ConWIP, are comparatively evaluated via Fuzzy Analytical Hierarchy Process. Finally, applying intelligent methods, as a novel approach in PPCP development, the evaluation procedure was realized by an Adaptive Neuro-Fuzzy-Inference System (ANFIS) model.

All the three approaches show the effectiveness of HIPCP mechanisms for minimizing the inventory level, lead time, and backlogged orders, and maximizing the responsiveness to actual demand in the studied case. The optimum surface of performance for alternatives based on criteria domain is found.
