Problems are investigated with the use of surveys being carried out in 900 sales points according to author＇s DORED （DORED-dobre rozwiazania dla dostaw in Polish, good solutions for delivery in English） program performance. The DORED program has been mentioned for the first time in Logistics （a Polish newspaper） in February, 2005. The developed topic has been the pilot project of DORED program. That was in Wroclaw City （Poland）, where the regions of Przedmiescie swidnickie were the first test of method of the DORED program. The mentioned topic has encompassed the city logistic problems, land transportation and movement organization performance in the city centres.展开更多

Appealing to Pontryagin maximum principle in control theory, the authors obtain the closed-forms of all optimal decisions the firm should make. Furthermore, the optimal production rate and optimal sales rate are both equal to the demand rate, which is caused by the optimal pricing policy during the whole horizon, and the optimal pricing path is increasing with the cost of installing a unit of capacity. Furthermore, numerical analysis reveals the visual impression of the relationship of the parameters.展开更多
