Fabrication Cycle Time and Shipment Decision for A Multiproduct Intra-Supply Chain System with External Source and Scrap

Abstract

Managers of today’s transnational firms, facing competitive global business environments, always intend to optimize their intra-supply chain systems to meet customers’ multiproduct demands with perfect quality goods, timely delivery, and minimum fabrication-shipping expenses. In the production units of intra-supply chain systems, random scraps are inevitable due to various unforeseen factors. Also, since the in-house capacity is limited, implementing a partial outsourcing plan can help release machine workloads, smooth production schedule, and reduce fabrication uptime. Inspired by these facts, this study explores an intra-supply chain system with random scraps and an external source. We build a mathematical model to portray the characteristics of the studied problem. Model analyses and the renewal reward theorem help us to obtain the expected system cost function. Optimization techniques and Hessian matrix equations are used to jointly decide the optimal cycle time and shipment policy that minimize the expected system cost. Through numerical illustration, we expose the individual and joint impact of diverse system features on the optimal operating policies and other crucial parameters of the studied problem, thus, facilitate managerial decision makings.

Investigation of environmental potentials on supply chain of textile and yarn industry using smart and sustainable life cycle assessment

“…Here the best supplier is exhibiting three times less sustainable environment potential than the worst one in optimizing the sand selection of better circular supply chain models by optimizing waste handling activities, indirect transport to environmental losses and usability of discarded products in this LCA methodology. The regenerated and random scraps became unavoidable while incorporating intra-supply chain systems (Chiu et al, 2020). The mathematical model is developed to govern the scraps, releasing machine workloads and scheduling production schedules.…”

Incorporating Outsourcing Strategy and Quality Assurance into a Multiproduct Manufacturer–Retailer Coordination Replenishing Decision

“…As a result, the total delivery and stock holding cost were reduced without increasing the stock-out risk. Additional recent works [29][30][31][32] studied various natures of intra-supply chain or vendor-buyer integrated types of systems. The urgent need for a precise model to help managers of present-day transnational firms make efficient and cost-effective multiproduct manufacturing and delivering decisions.…”
