Today’s company competiveness is favoured by product customisation and fast delivery. A strategy to meet this challenge is to manufacture standard items to stock for product customisation. This configures a hybrid environment of make-to-stock and make-to-order. To explore the advantages of this requires good understanding of production control. Thus, we study production under hybrid MTS-MTO, or...

The volatile fossil fuel cost, the growing energy demand, rise in energy security issues and the increasing concerns of environmental issues have led man-kind to look for alternative energy sources. Wind energy is one of the alternatives. Prior to installment of a wind turbine, careful wind resource assessment and energy output estimation must be carried out in order to make judicious decisions...

Due to the ongoing trend towards increased product variety, fast-moving consumer goods such as food and beverages, pharmaceuticals, and chemicals are typically manufactured through so-called make-and-pack processes. These processes consist of a make stage, a pack stage, and intermediate storage facilities that decouple these two stages. In operations scheduling, complex technological constraint...

Dusun Batu Saeng, Tanggamus, Lampung is one of the areas that utilize potential surrounding natural resources. One potentials used river water which as a Micro Hydro Power Plant (PLTMH). However, source electrical energy has been for 10 years d...

The thesis presents a novel set-theoretic formalization of (propositional) hybrid planning – a planning framework that fuses Hierarchical Task Network (HTN) planning with Partial-Order Causal-Link (POCL) planning. Several sub classes thereof are identified that capture well-known problems such as HTN planning and POCL planning. For these problem classes, the complexity of the plan-existence pro...

The planning of production capacity for a company has been extensively discussed in literature. Seasonal demand of products or seasonal availability of input materials can make the problem even more challenging, as due to a constant need for capacity adjustments. For example, in contrast to conventional chemical processes, the use of biomass has several distinct characteristics like a time depe...

Increasing cost pressures have led supply chain managers to focus on running increasingly lean and efficient supply chains, with minimal inventory. Indeed, more and more firms are relying on pull or make-toorder (MTO) supply chains to minimize cost and waste. At the same time, increasing competitive pressures are leading to an increased emphasis on customer service. An important element of cust...

The capacitated lot sizing policy is pivotaltostochastic production planning. This paper attempts to formulate a general lot sizing model for a stochastic MTS (make-to-stock) manufacturing environment under demand uncertainty. To better reflect real-world manufacturing, general distributions are used as a substitute for unrealistic theoretical assumptions on involved random variables. Instead o...
