Fuzzy set theory is primarily concerned with how to quantitatively deal with imprec ision and uncertainty, and offers the decision maker another tool in addition to the classical deterministic and probabilistic mathematical tools that a re used in modeling real-world problems. The present study investigates a fuzzy economic order quantity model for deteriorating items in which demand increases ...

This paper aims to enable the decision maker of an integrated vendor–buyer system, under Consignment Stock (CS) policy, to make the optimal/sub-optimal production/replenishment decisions where the buyer places a space limitation to the vendor and the lead-time is controllable with an extra investment. Within any production cycle, the vendor produces at a finite rate and ships the outputs to the...

Purpose: The purpose of this paper is to extend the analysis of the distribution-free newsvendor problem under the circumstance of customer balking, which usually occurs when customers are reluctant to buy products if the available inventory falls below a threshold level. Design/methodology/approach: A new tradeoff tool is provided as a replacement of the traditional one to weigh the holding co...

Supply chain management aims to integrate environmental thinking with efficient energy consumption into supply management. It includes a flexible manufacturing process, more product delivery customers, optimum consumption, and reduced waste. The process can be made through volume agility. In this scenario, production cannot constant, the concept of agility, is taken as decision variable under e...

This paper presents the findings of a study with a Unilever bottle-filling plant and its key bottle supplier, ALPLA. The purpose of this paper is to investigate the complexity associated with before and after integration. The nature of the complexity alters as the supplier-customer relationship changes, in this case from pre-integration to post-integration system. The areas in which complexity ...

Motivated by the operational environment in high-tech industries, this paper examines the coordination between and when time to market and capacity marketing operations utilization are both main factors. In contrast to earlier joint lot-sizing literature which focuses on price-quantity coordination, our model captures the inter-relationship between order quantity, capacity level, and lead-time....
