Production planning with lot-sizing and scheduling in industries where the cleaning times depend on the sequence of the products can be modelled as a mixed integer problem. However, this problem is very hard, and even small instances cannot be solved exactly in a reasonable time. We propose a division of the whole production planning problem into its two subproblems, and to solve each them inde...

Multi-criteria decision analysis (MCDA) is a decision aid frequently used in the field of forest management planning. It includes the evaluation of multiple criteria such as the production of timber and non-timber forest products and tangible as well as intangible values of ecosystem services (ES). Hence, it is beneficial compared to those methods that take a purely financial perspective. Accor...

  One of the main elements of each supply chain is production. Production planning in multi-products process industries in which products are subjected to the complicated operational constraints is a very hard work because production of computed optimal volume should be compatible with operation scheduling constraints of production system. Thus, integration idea has been proposed for required d...

One of the most studied issues in production planning or inventory management is to get the lowest possible cost with the satisfied service rate (less waiting time). Analyzing and comparing two main stream methods which are used for solving complex system – System Dynamics Model(SDM) and Agent Based Model (ABM), studying the characteristics of these two methods, and attempting to transfer a com...

Due to the increase of a variety of demands from downstream customers, the enterprises are necessary to expand more capacity of their factories by way of adding more plants or outsourcing. Many enterprises encounter great difficulties in production planning because manufacturing environments have changed from traditional single-plant to current multi-plants. Therefore, the company may possess m...

In this paper, a general multi-level decomposition based framework has been proposed for integration of planning and scheduling in a multi-site, multi-product plant, with applications to paper manufacturing. The problem involves complex issues relating to large-scale production in a hybrid flowshop configuration, decisions relating to minimizing trim losses, while maintaining on-time delivery o...

Crew scheduling is an important production planning of airlines. Being optimized crew scheduling could make full use of human resources, and reduce operating costs. The traditional airline crew scheduling model is deterministic and does not include potential disruptions due to weather, air traffic control, etc. To take into account of effects of random factors such as weather, air traffic contr...

demand management is one of the main subjects in marketing which affects the operations performance of an organization considerably. in the classic production planning approach, demand is considered as an exogenous factor in planning, while in the new approach, it is a factor that can be controlled. in this paper, we focus on a new approach in supply chain planning and present an integrated pro...

Complexity is one of the most important issues of any production planning. The increase in complexity of production planning can cause inconsistency between a production plan and an actual outcome. The complexity generally can be divided in two categories, the static complexity and the dynamic complexity, which can be computed using the ant ropy formula. The formula considers the probability of...
