Optimizing the Raw Materials Purchases and Advertising Campaign of Enterprise

Анотація

The publication is concerned with elaboration of a method for simulation of the logistics system (LS) of enterprise. The article is aimed at development, using the approach by J. Forrester, of an economic-mathematical model of the enterprise’s production activities taking into account all the main links of its LS, starting with the composition of raw materials; application of the developed model to simultaneously optimize the purchase of raw materials and the duration of an advertising campaign. The publication formulates a system of equations that describe the enterprise’s LS. Simulation modeling is implemented using a system of mathematical equations, which constitute the basis of computer programs, allowing to model the work of LS in the mode of «simulation» of the structure, taking into account the parameters of the LS. The optimization task of defining the maximum economic efficiency as a function of parameters that determine the purchase of raw materials and the timing of an advertising campaign is formulated. Calculations of the time dynamics of all the pace of the logistics system (production, transportation), as well as the dynamics of the levels of goods in the wholesale and in retail chains, are accomplished.
