Integrating production scheduling and transportation procurement through combinatorial auctions

Abstract

This study uses the winner determination problem (WDP) to integrate auction transportation procurement with decisions related to production scheduling. The basic problem arises when a manufacturer has to clear a combinatorial auction to decide whether to cover transportation needs by using the in‐house fleet or to procure transportation through auction. Thus, the manufacturer should include an additional decision level by integrating the WDP with production scheduling to gain efficiency and achieve savings in the logistics system. To the best of our knowledge, this is the first time production and transportation procurement problems are being solved simultaneously in an integrated manner. The study proposes a mathematical formulation and develops two heuristic approaches for solving the integrated problem. Extensive computational experiments and sensitivity analyses are reported to validate the model, assess the performance of the heuristics, and show the effect of integration on total cost.

Optimisation models for the procurement through reverse combinatorial auctions in the logistics and food industries

“…Moreover, the authors proposed three metaheuristic approaches for its solution. The last work we are aware of was developed by Triki et al (2020) in which the SLSP model has been embedded within a production-distribution framework while involving occasional drivers that contribute in accomplishing part of the delivery tasks. Their study has shown that the SLSP can gain efficiency, expressed in terms of total cost minimization, by coordinating the production and delivery activities.…”

Integrated Fuzzy AHP-TOPSIS Method to Analyze Green Management Practice in Hospitality Industry in the Sultanate of Oman

“…Transportation is considered one of the important elements that have a fundamental role in designing the supply chain [28]. There are critical impacts associated with transportation such as global warming, environmental deterioration, health effects (physical, emotional, mental, spiritual), and greenhouse gas emissions [23].…”

A combinatorial auction‐based approach for ridesharing in a student transportation system

“…Multi‐objective optimization models were presented by Ignatius et al [19] who considered the cost, market fairness, and market confidence as criteria for choosing the winning bids. Ledyard et al [27] and Elmaghraby and Keskinocak [10] developed specialized models for real‐life applications and Triki et al [46] embedded a WDP within a production‐distribution planning scheme.…”
