in today's globalization, an effective integration of production and distribution plans into a unified framework is crucial for attaining competitive advantage. this paper addresses an integrated multi-product and multi-time period production/distribution planning problem for a two-echelon supply chain subject to the real-world variables and constraints. it is assumed that all transportations a...

Cheese-making technology aims to preserve milk so that consumption can be postponed for periods from a few days to several months. The preservation of the product is obtained mainly through lactic acidification and limited dehydration. These operations take place during the two first steps of processing, the setting (or coagulation) and draining phases. For many cheese types, a third phase know...

an integrated model considers all parameters and elements of different deficiencies in one problem. this paper presents a new integrated model of a supply chain that simultaneously considers facility location, vehicle routing and inventory control problems as well as their interactions in one problem, called location-routing-inventory (lri) problem. this model also considers stochastic demands ...

A new mixed-integer programming (MIP) formulation is presented for the production planning of single-stage multi-product processes. The problem is formulated as a multi-item capacitated lot-sizing problem in which (a) multiple items can be produced in each planning period, (b) sequence-independent set-ups can carry over from previous periods, (c) set-ups can cross over planning period boundarie...

Existing product derivation approaches focus on support for single users resolving variability based on a single variability model. However, in practice multiple users perform product derivation of large-scale systems with system-ofsystems architectures in a distributed and asynchronous manner. It is infeasible to describe the variability of such multi product lines with one integrated model. R...
