in this paper mathematical extensions and generalizations of the pearl-reed model for'growth with saturation are discussed. the derived differential equation are of bernoulli and riccati type that owing to their special forms could be explicitely integrated resulting in closed form solutions. the asymptotic bahaviour of the system in each case is briefly examined and the results are compar...

occurrence of chaotic behaviors because of fluctuations creation and their intensified transfer along the chain is one of the main causes of inefficiency of material requirements planning (mrp) based supply chains. one of the reasons of the inefficiency is the lumpiness phenomenon. through this phenomenon, some parts have an irregular production schedule, with nothing produced in some periods a...

This paper examines connections between data-driven models for analyzing a firm's strategic plans, which use activity-based costing and mathematical programming, and the resource-based view of the firm. After brief reviews of the three disciplines, extensions of activity-based costing methods to mathematical programming models for strategic resource planning are discussed. Applications of these...

substitution management planning, as one of the important issues in manpower planning, is referred to as a process of filling the gaps and fulfilling the needs of very crutial and key elements of organization in managerial levels. meeting the needs by means of using external and internal manpower of the organization seems to be rational. however, it has some advantages and disadvantages. this p...

calculating total cast of bank resources procurement methods which include current -free loan deposit, saving interest-free loan deposit, regular and net short-term investment deposit, long-term investment deposit and surety bond cash deposit and presenting their optimal integration require precise scientific studies. hence, this study is an attempt to know which methods are the best optimal in...

This report aims to discuss the strengths and weaknesses of the application of systems modeling to analyze the effects of training on performance. The simplifications inherent to the modeling approach are outlined to question the relevance of the models to predict athletes' responses to training. These simplifications include the selection of the variables assigned to the system's input and out...

This paper presents a CBP-BDI planning model which incorporates a novel artificial neural network. The CBP-BDI model, which is integrated within an agent, is the core of a Multiagent System that allows managing the security in industrial environments. The BDI model integrates within a CBP engine of reasoning that incorporates ANN-based techniques, and in this way it is possible to adapt past ex...
