“…In contrast to the previous work, paper [7] presents a method of cost planning (dynamic programming) which considers environment-related costs as internal costs. These costs include hydrocarbon emissions, the cost of energy consumption and the costs associated with the wastes of material resources.…”

Cost price reduction is one of the ways to improve the competitiveness of products. It is possible by establishing the set of factors affecting the production costs at an industrial enterprise and building on this basis a mathematical model of in-house cost management. The study objective was to develop and substantiate an economic-and-mathematical model of management to minimize the enterprise costs taking into account the utilization of secondary resources obtained in the production of basic products. The model consists of two stages. At the first stage, full costs of production of basic and additional products are determined. The peculiarity of this production implies the generation of significant amounts of secondary resources that have both independent value and opportunities for their use in the main technological process. This leads to complex material flows within the production process, which were accounted for in the study with the help of an adapted "cost-output" balance model. A plant can function with the use of a variety of raw materials which differ in both prices and rates of the output of basic products and secondary resources. This brings about the problem of finding an optimal combination of input resources to minimize costs or maximize profits. The problem is solved in the second stage. It is formalized as a linear programming problem. It features the provision of the ability to establish indicative plans of production of both main products and by-products. The model was tested on the example of coke-chemical plants producing coke of KDM-2 grade with 6 % humidity content and KDM-1 grade coke of improved quality as the main products. Coke oven gas, coke fines, beans, and sludge are produced as by-products. After purifying the coke oven gas, it is further used in the production of heat and electricity, compressed air, and a fuel for coke ovens. Thus, the produced fuel and energy, utilizable material resources, and circulating water supply are secondary resources. A certain portion of by-products is sold to third parties. When applied, the model will make it possible to improve the efficiency of cost management at enterprises

“…Extensive research has been done on modelling and analysis of manufacturing system (Hopp and Spearman, 1996;Shi and Zhou, 2009;Jaber and Khan, 2010), scheduling and material and maintenance requirement planning (Shi, 2006;Xu et al, 2018;Sun et al, 2018), and material handling systems (Poon et al, 2011;Heragu et al, 2011;Shahbazi et al, 2016), lean manufacturing (Green et al, 2010;Sartal et al, 2018). Much of the previous works focus on performance metrics of isolated manufacturing system which is based on the nature of the methods used in the respective manufacturing processes.…”

Current systems lack the required indices to measure its efficiency and highlight the areas of inefficiency in the system. The paper is aimed at improving the overall performance of manufacturing system by suggesting methods for integrated improvement in above two factors. This paper establishes performance indices for measuring energy efficiency and productivity of the system, which uses easily available sensor data from the production line. The energy structure and effects of downtime events on the production line has been analyzed to develop energy and productivity performance indicators. The indices are utilized to identify the machines which is most power inefficient and results in maximum production loss of the system. These indicators are utilized to illustrate our method for improving productivity and concepts of downtime-bottleneck and power-bottleneck. The methods proposed are verified by simulation studies.

“…Some address the maximization of the Net Present Value NPV of mining projects (Samavati, Essam, Nehring, & Sarker, 2017;Whittle, Brazil, Grossman, Rubinstein, & Thomas, 2018). Others address the consideration of sustainable development aspects "economic, social, environmental and lately safety" (Kazanin, Rudakov, & Kolvakh, 2018), which are firmly related to the UPL, explaining the needs to consider them in mine planning and mining design for a sustainable mining industry (Adibi, Ataee-Pour, & Rahmanpour, 2015;Kamenopoulos, Agioutantis, & Komnitsas, 2018;Popovic et al, 2015;Rahmanpour & Osanloo, 2017;Xu et al, 2018).…”

Mining industry importance stems from the fact that it forms the basis of all materials used by humankind, including the agro-industrial sector, where products such as phosphates are behind a significant part of all modern agriculture. Despite its high economic importance, the constraints of its activity make it be considered one of the most challenging and dangerous industries. The main optimization problems in open pit mining design consist on the determination of the ultimate pit limit for exploitation, and mining block sequences for the production schedule, where safety management decision system needs to be integrated. The proposed protocol provides the procedure that will be used to conduct one or more systematic reviews according to the PRISMA statement, to prove the effectiveness of optimization solutions on open pit mining production and occupational safety. The search will be carried out in eight electronic engineering databases, using eight combinations of appropriate keywords for the topic to achieve the main goal. The selection process, data extraction, and data synthesis are described. advantages (improvement in mine planning and safety in the long and short term), the effectiveness of implementation (cost and time). Outcomes of this study will contribute to the mining industry through research in order to improve mine planning and safety in long term and short term.
