The collective effect of rework, expedited-rate, external source, and machine failures on manufacturing runtime planning

Abstract

Production managers face the growing trend of rapid-response orders and inevitable production defects and failures; they must carefully measure these factors’ effects to minimize operating expenditures and operational disruption. Inspired by assisting producers decide the optimal runtime policy under these real situations, this work investigates the collective impact of rework, expedited-rate, external source, and machine failures on such a specific fabrication system. A partial outsourcing and expedited manufacturing rate are considered in the studied system to reduce the batch fabricating time. Additionally, defects rework and repair failure machines are implemented to retain the quality and avoid production disruption. Our research scheme consists of (1) developing a model for the mentioned manufacturing characteristics; and (2) analytical and optimization techniques for deciding the best batch runtime decision by minimizing the system’s overall expenses. Lastly, we provide numerical examples to demonstrate the model’s applicability and disclose important, in-depth characteristics that facilitate managerial decision-making.

Replenishment-shipment decision for a multiproduct producer-client coordinated FPR model with postponement, rework and subcontracting

“…Lastly, the study offers a numerical demonstration and sensitivity analyses for the research results. Additional works (Nachiappan et al, 2008;Singh and Singh, 2013;Chiu et al, 2021;Di Nardo et al, 2021;Uzen et al, 2021;Aljumah et al, 2022;Chiu et al, 2022b;Comert et al, 2022;Lin et al, 2022b;Riaño et al, 2022;Seçkin and Seçkin, 2022) studied various random faulty goods produced and quality assurance actions, and shipping policies influence fabricating systems and supply chains' operations and management. Few earlier works examined the collective/individual impact of scraps, subcontracting strategy, rework, and postponement on the multiproduct replenishingtransportation decisions; we intend to fill the gap.…”
