“…There is increasing focus now, however, on the role of energy in affecting the productivity and competitiveness of a supply chain [4,10,11]. Particular attention is given to the potential for demand side management techniques, such as energy efficiency of products and process [12], responsive consumption of energy in response to market signals through smart metering and alternative technologies [13] and also as revenue generating streams, either indirectly through the production process [14] or directly from alternative energy technologies [15]. However, these demand-side management techniques do not reduce the vulnerability of production systems to energy security: dependence on energy in the production system increases as slack is removed from the system and the relative value of energy becomes more significant [8].…”

“…In that model the supply chain planning is a strategic one-period (one year) problem, including decisions about supply of materials, production, and distribution. Waldemarsson et al (2013) simplified the distribution problem but extended and developed the model by Gunnarsson et al (2007). This extension includes decisions about the energy mix and by choosing the energy input at the pulp mills.…”

To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users. The process industry sector is one of the largest users of energy, and thus important to analyse. Process industries are also capital intensive and operate on large and expensive process equipment, making it imperative to plan their production well in order to reach preferable capacity utilisation. Therefore this dissertation strives to locate the most important energy management issues for the long term profitability of process industries, and investigates the symbiotic effects of including energy issues in production and supply chain planning.Three different studies at three case companies are carried out, analysed, and presented in five papers. The cases represent the process industry sectors: chemicals, pulp, and steel. Both qualitative case study methodologies as well as quantitative mathematical modelling and optimisation approaches have been practiced. The research questions are analysed from both an energy system and from a production process point of view, separately as well as combined. Energy is somewhat considered to be the main workforce for process industries and this dissertation exemplifies some of its most important dimensions in this context. Several prerequisites for putting energy management on the strategic agenda are located in a specialty chemical industry where the importance of introducing a strategic perspective on energy, the way energy is used, and the possibilities of increasing alternative revenue from utilising by-and/or co-products differently are pinpointed. Approaches for including energy issues in planning processes are also suggested in terms of a MILP model for the entire supply chain of a pulp company, including decisions on purchase and transportation of raw materials, production allocation, energy mix, and distribution. Another example is presented based on the perspectives of economics of scale and lot sizing through economic order quantity principles in a steel company. By using real company data, energy smart approaches in planning and scheduling are developed with respect to the most important intersections between the production processes and their supporting energy system. The accumulated resource intensity and embedded energy could, and probably should, hence be more fairly reflected in the product price. The research finally shows some possible impact with including energy issues in a production and supply chain planning model. By planning differently, production prioritisations can be done, and it is not only possible without any large investments, but also prosperous with savings on both energy and money within reach.To conclude, planning of production and supply ch...
