Order Sequencing

Die logistische Leistungsfähigkeit und Wirtschaftlichkeit einer Produktion werden durch die Auftragsreihenfolgebildung beeinflusst. Mathematische Modelle zur Beschreibung der Auswirkungen verschiedener Reihenfolgeregeln auf logistische Zielgrößen einzelner Arbeitssysteme können zur Ableitung von Reihenfolgestrategien für mehrstufige Produktionen genutzt werden. Die Festlegung der Strategie erfolgt dabei durch eine bewusste Positionierung im Spannungsfeld zwischen Produktivität und Termintreue.   The logistical performance and economic efficiency of a production system are influenced by order sequencing. Mathematical models to describe the effects of different sequencing rules on logistic target variables of individual workstations may be used to derive sequencing strategies for multi-stage productions. The strategy is defined by conscious positioning in the conflicting fields of productivity and schedule compliance.

The article describes the methodology for describing the economic indicators of management effectiveness and decision-making under conditions of complex multi-stage productions. The algorithm and the forecast model of the need for production resources are presented, that allow providing more complete information on costs and help in pricing for various products, significantly reducing the response time to economic and technological situation changes. Characteristics of technology parameters are linked to a multi-stage production process. As the semi-finished product passes through the processing stages, the values of the technological factors are fixed. Methods for estimating the influence of parameters of complex spatially-distributed systems on costs are presented. Important elements of costs that affect the product value are determined. Detailing the cost elements for the technological operations under study is carried out, the boundaries, where the largest amount of resources is spent, are determined.

An overview of world experience in the development and implementation of emission monitoring systems for industrial enterprises, based on mathematical models is presented. The main problems of such systems have been analyzed, their advantages and disadvantages have been revealed. The authors have demonstrated that at Russian enterprises, the introduction of predictive emission monitoring systems was possible at the initial stages of transition to BAT as part of the digital technologies’ integration in production processes.

SUMMARYThe objective of the present study was to determine the optimal culling strategy in relation to biological and economic efficiency (BE and EE, respectively) and annualized net revenue (AN) in the Japanese Black cow–calf production system with special reference to the beef quality of culled cows. The herd model focused on two ways of mating: one-mating trial system (ONE) and continuous-mating trial system (CON). ONE assumed that heifers that fail to conceive are culled and cows that fail to conceive are culled at weaning of their calves, while CON assumed that mating continues until all females theoretically conceive. Least square means of carcass data of Japanese Black cows collected from a cooperative farm in Japan were used to estimate the carcass price of a cow by parity and Beef Marbling Standard (BMS) number. The simulation, assuming the current production situation in Japan, indicated that sales of culled cows accounted for 0·10–0·20 of total sales and was an important element in total production. Comparisons between ONE and CON showed that production efficiency in the current situation is higher in CON. The BE, EE and AN were higher in CON than in ONE. The two economic indicators were less sensitive to changes in annual discount rate but highly sensitive to changes in female calf price and BMS number of cows, indicating the importance of considering fluctuations in calf price and potential quality of culled cows’ carcasses when estimating the economically optimal parity of culling. The three indicators derived different optimal solutions even in the same mating trial systems, stressing the importance of choice of production indicators when determining the culling strategy and evaluating animal production.

This article is about the economics aspects on optimization of components production are nowadays very current issue. Article is about the criteria of economic efficiency of production of mechanical components for machine tools and CNC machines. The machinability of materials is considered to be a parameter which characterizes the machined material in the process of cutting and expresses the degree of machining effectivity in terms of material of a product and is expressed by mathematical model.
