The aim of this paper is to demonstrate that CP could be a better candidate than MIP for solving the master problem within a Benders decomposition approach. Our demonstration is based on a case study of a workforce scheduling problem encountered in a large call center of Bouygues Telecom, a French mobile phone operator. Our experiments show that CP can advantageously replace MIP for the impleme...

Abstract The safety of operations is vital in any process the oil and gas sector, especially given that increasingly more hydrocarbon reserves are discovered non-conventional remote Arctic locations. Safety systems designed as a part complex IT system for control. design these conducted form an engineering project. This research presents decision-making framework to facilitate formulating clear...

Goods from warehouses must be scheduled in advance, prepared, routed, and delivered to shops. At least three systems directly interact within such a process: warehouse workforce scheduling, delivery routing system. Ideally, the whole problem with preceding inventory management (restocking) would solved one optimization pass. In order make simpler, we first decompose total by isolating schedulin...

Along with the number of projects received and must be completed on time by PT. EKIOSKU, where project scheduling has been carried out using estimation method, so that it an impact results estimating time, human resources, estimated costs software are quite large. In addition, for tasksperformed manager, its still in inefficient verbal way because each workforce different abilities. Based exist...

This work is focused on workforce scheduling for assembly lines with the additional constraint of distancing. The aim to warrant necessary safety and health requirements due COVID-19. research stems within an industrial case in which a methodology has been developed objectives i) developing optimization model considering social distancing workers as part ii) investigating how can affect certain...

this study presents a detailed analysis of cost management for intensive cultivation activity in terms of tomato production. the main objective was to provide qualitative and quantitative costs obtained in the intensive cultivation of tomato. this methodology was structured by activity costs (soil preparation and planting, crop monitoring, harvesting, selling, etc.) through a study in greenhous...
