Since there has been tremendous progress in planning in the process industry during the last 25 years, it might be worthwhile to give an overview of the current state-of-the-art of planning problems in the process industry. This is the purpose of the current contribution which has the following structure: we start with some conceptional thoughts and some comments on special features of planning...

In this paper, production planning and scheduling problems are addressed through a hierarchical framework. The planning problem aggregates orders in the planning period and considers uncertainty utilizing a multi-stage stochastic programming formulation where three stages are considered with increasing level of uncertainty. The planning model includes material balances and time horizon constrai...

Multi-agent systems often require runtime planning, which remains an open problem due to the existing gap between planning and execution in practice. Extensive research has been carried out in centralised planning for single-agent systems, but so far decentralised multi-agent planning has not been fully explored. In this paper, we extend existing multiagent platforms to enable decentralised pla...

We study a single product two-period production/inventory model, in which the demands at each period are independent random variables. To optimally satisfy these random demands, quantities can be produced at the beginning of each period using slow or fast production mode, under capacity constraints. In addition to the usual decision variables for such models, we consider that a certain quantity...

Aggregate production planning (APP) is considered as mid-term decision planning. The purpose of multiperiod APP is to set up overall production levels for each product category to meet fluctuating or uncertain demand in the near future and to set up decisions and policies on the subject of hiring, lay-offs, overtime, backorder, subcontracting, facilities and inventory. In this study, we develop...

the territory of serbia is vulnerable to various types of natural hazards and the risk is not equal across the entire territory; it varies depending on the type of hazard and the expected potential for damage. the first aim of this research was to determine the geographical distributions of the major types of natural hazards. seismic hazards, landslides, rock falls, floods, torrential floods...

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...

this paper is in search of designing the cellular manufacturing systems (cmss) under dynamic and flexible environment. cm is proper for small-to-medium lot production environment that helps the companies to produce variable kind of productions with at least scraps. the most important benefits of cm are decline in material handling, reduction in work-in-process, reduction in set-up time, increme...
