“…Numerical illustrations were offered to show the difference among three models and their applicability. Other studies (Kuhn and Liske, 2011;Stažnik et al, 2017;Díaz-Mateus et al, 2018;Morales et al, 2018;Rahimi and Fazlollahtabar, 2018;Al-Odeh and Altarazi, 2019;Mosca et al, 2019) also examined different features of multi-shipment effect on various fabrication-transportation and supply-chain systems. Few studies have investigated the joint influences of unreliable machine, scrap, outsourcing, and multiple shipments on the intra-supply-chain planning, this study aims to fill the gap.…”

Operating in today's highly competitive global markets, transnational enterprises always seek to optimize internal vendor-buyer coordinated systems to ensure timeliness and quality deliveries, given the reality of unreliable machines and limited capacity. To facilitate accurate decision making to help organizations gain competitive advantages in such situations, this study explores an intra-supply-chain problem featuring a partial outsourcing batch fabrication plan, random scrap, Poisson-distributed breakdown rate, and multiple shipments of end-product. First, we build a model to characterize the problem clearly. Then, we carry out formulations, analyses, and derivations of the model to attain the problem's cost function. We then use differential calculus and propose a specific algorithm to confirm the convexity of the obtained cost function and derive the optimal runtime. Finally, we offer a numerical illustration to demonstrate the result's applicability for other business circumstances. Additional elements of the problem are then discussed, including the individual and combined influence of variations in scrap, outsourcing, breakdown, and shipping frequency. The features of an optimal operating policy and cost relevant parameters are now revealed to assist management with strategic planning and decision making in real-world intra-supply-chain environments.

“…As a result, different models were classifi ed and various critical issues were pointed out for future study. Other studies [31][32][33][34][35][36][37][38] also investigated supply chain systems with different features. This present study aims at offering managers a decision model to help them accomplish critical operation goals, such as keeping fl exible fabrication schedule, retaining product quality and timely delivery, and lowering total operating expenses.…”

In order to gain competitive advantages, managers of present-day supply chain systems need to achieve critical operation goals, such as keeping fl exible fabrication schedule, retaining product quality, maintaining timely delivery, and lowering overall operating costs. Inspired by these factors, this study developed a decision model for managers to investigate the joint impacts of quality-assured issues, overtime, and multi-shipment plan on optimal fabrication-shipment policy and on diverse system parameters of the economic production quantity (EPQ)-based supply chain system. An imperfect fabrication process producing perfect quality, repairable, and scrap items is assumed in the proposed system, along with assumptions of a fl exible overtime schedule to partially expedite fabrication rate and a discontinuous multi-delivery policy for distributing end products. With a help from mathematical modeling and optimization method, the closed-form optimal fabrication-shipment policy is derived. A numerical example was employed to demonstrate applicability of our result and to expose critical managerial information of the system for supporting decision-making.

“…There is also no unique solution for decision-making related to risks for each transportation chain, as it depends on various factors, such as the number of links, phases of the supply chain which it connects, distance etc. (Stažnik et al, 2017).…”

“…The problem of risk management is a global problem that requires global solutions (Stažnik et al, 2017). Systemic risks within a supply chain and transport networks are common and are characterized by an unexpected trigger event and a network setup that cannot absorb the shock and knock-on effects.…”
