Using relatively simple and widely used models, we illustrate how carbon emission concerns could be integrated into operational decision-making with regard to procurement, production, inventory management. We show how, by associating parameters various decision variables, traditional models can modified support that accounts for both cost footprint. examine the values of these as well regulatory control policies affect emissions. use study extent which reduction requirements addressed...

In this note, we study the concurrent determination of pricing and inventory replenishment decisions for a perishable product in an infinite horizon. Demands consecutive periods are independent influenced by prices charged each period. particular, treat price as decision variable to maximize total discounted profit. We analyze optimal solution-structure two-period lifetime problem from insights gained numerical experiments, develop base-stock/list-price heuristic policy products with...

In this article, we study the joint pricing and inventory control problem for perishables when a retailer does not sell new old at same time. At beginning of period, makes replenishment decisions, end decides whether to dispose ending or carry it forward next period. The objective is maximize long‐run average profit. Assuming zero lead time, propose an efficient solution approach problem, which also generalized solve three extensions basic model. A feature present that consider explicitly...

Problem definition: We consider the effects of strategic inventory (SI) in presence chain-to-chain competition a two-period model. Academic/practical relevance: Established findings suggest that SI may alleviate double marginalization and improve efficiency decentralized distribution channel. However, no studies role under competition. Methodology: build model consisting two competing supply chains, each with an upstream manufacturer exclusive retailer. The retailers compete on either price...

We study a risk‐averse newsvendor problem where demand distribution is unknown. The focal product new, and only the historical information of related products available. aims to maximize its expected profit subject risk constraint. develop model with value‐at‐risk constraint propose data‐driven approximation theoretical model. Specifically, we use machine learning methods weight similarity between new previous ones based on covariates. sample‐dependent weights are then embedded approximate...

An importer in Hong Kong employs vehicles, all from external transport companies, to deliver products its customers geographically scattered different locations. The delivery plan needs simultaneously minimize the total traveling cost and balance profits among companies. This transportation practice engenders a new variant of vehicle routing problems, called problem with outsourcing profit balancing (VRPOPB). are balanced by maximizing minimum unit which can effectively avoid occurrence...

Abstract In this work, we study manpower allocation with time windows and job‐teaming constraints. A set of jobs at dispersed locations requires teams different types workers where each job must be carried out in a preestablished window specific length for completion. is satisfied if the required composite team can brought together job's location duration within window. The objective to minimize weighted sum total number traveling time. We show that construction heuristics used simulated...

A manufacturer may manage consumer deliberation decision through the wholesale price, empowerment, and product qualities.

The present study investigates the benefit of joint decision making regarding whole blood collection and platelet production at a center. We consider center that faces two types demands, differing in their freshness requirements shortage penalty costs. fully characterize structure optimal policy collection, production, inventory issuing, rationing disposal. find quantity each period is nonincreasing levels platelets but interestingly, effort may increase with on‐hand level. demonstrate real...

Trade globalization has brought a surge in Free Agreements (FTAs). Although trade agreements have been studied extensively from the economic point of view, there is very little operations management literature on effect FTAs at firm level. In this work, we present material sourcing model which can be used by companies. The addresses local content or value-added requirements for concessions, and motivated Japan-Singapore Economic Partnership Agreement FTA. We provide solution techniques...

Abstract In this study we solve the multi-item capacitated dynamic lot-sizing problem, where each item faces a series of demands, and in period multiple items share limited production resources. The objective is to find optimal plan so as minimise total cost, including inventory holding fixed setup cost. We consider both single-level multi-level cases. case, some are consumed order produce other therefore face internally generated demand addition external demands. propose simple three-stage...
