A software vendor sometimes contracts the maintenance of a software product that other software vendors gave up maintaining due to costs etc. In such case, the vendor must estimate costs of maintenance before contracting. However, due to lack of an objective measure, an expert estimates the cost on the basis of his/her experience. We will propose some metrics for estimating maintenance effort. ...

Cost estimation process becomes a crucial factor in any software development project. An effective software estimate provides the information needed to design a workable software development plan. An effective software estimate provides important information for making project decisions, projecting performance and defining objectives and plans. Without the proper guidance in a project, the resu...

Estimation of cost and time to develop a software product P is a well known problem. Among the possible ways to do it is analogy with old finished projects. We describe an experiment using different versions of the Fuzzy c-Means algorithm, to find projects similar to P . Then the information about these projects is used to estimate the effort needed to build P .

objectives: the present study aimed to provide an estimation of the current financial burden of renal transplantation therapy for insurance organisations.methods: an excel-based model was developed to determine the treatment costs of current clinical practice in renal transplantation therapy (rtt). inputs were derived from ministry of health and insurance organizations` database, hospital and p...

One of the most important processes in the early stages of construction projects is to estimate the cost involved. This process involves a wide range of uncertainties, which make it a challenging task. Because of unknown issues, using the experience of the experts or looking for similar cases are the conventional methods to deal with cost estimation. The current study presents data-driven metho...

Given a geometric Brownian motion wealth process, log-Normal lower bound is constructed for the returns of regular investing schedule. The distribution parameters this are computed recursively. For dollar cost averaging (equal amounts in equal time intervals), closed form. A lump sum (single amount at 0) schedule described which achieves terminal that matches indicated by bound. Results applied...
