Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

A manufacturing inventory model with shortages with carrying cost, shortage cost, setup cost and demand quantity as imprecise numbers, instead of real numbers, namely interval number is considered here. First, a brief survey of the existing works on comparing and ranking any two interval numbers on the real line is presented. A common algorithm for the optimum production quantity (Economic lot-...

In this paper, we establish some recurrence relations for single and product moments of generalized order statistics from pth order exponential distribution. Further the results are deduced for the recurrence relations of record values and ordinary order statistics and using a recurrence relation for single moments we obtain characterization of pth order exponential distribution.

This research paper investigates a duopolistic market characterized by vertical product differentiation. The study considers both qualities and consumer preferences represented as one-dimensional intervals. focus is on analyzing the equilibrium in duopoly game with convex production costs. In this setting, each firm has option to present multi-product strategy consisting of quality–price pairs,...

This paper investigates the effect of product substitution in the single-period ‘newsboy-type’ problem in a fuzzy environment. It is supposed that the single-period problem operates under uncertainty in customer demand, which is described by imprecise terms and modelled by fuzzy sets. To perform this analysis, we consider the fuzzy model for two-item with upward substitution. This upward substi...

To determine the effects of a home grown Electronic Meeting System (EMS) on product quality, we surveyed 40 software development teams and their project sponsors. Teams were part of a single software development laboratory which itself is part of a large international organization. A model of intra-group conflict management which incorporates using an EMS to reduce work uncertainty is a signifi...

In this paper, an iterative and recursive method for the application of a System of Systems (SoS) view to medical Product Development will be presented. Using a top-down approach, the method starts with the definition of business processes and leads to the definition of single systems architectures which satisfy requirements on a System of Systems level. A modeling technique based on the use of...

In this paper we derive a new algorithm for constructing a uni-tary decomposition of a sequence of matrices in product or quotient form. The unitary decomposition requires only unitary left and right transformations on the individual matrices and amounts to computing the generalized singular value decomposition of the sequence. The proposed algorithm is related to the classical Golub-Kahan proc...

Recently stream logging has been referred to widely by web based and product based companies. Stream logging is one of the most important topic of agenda in business re-engineering. Business re-engineering is done in order to improve the effectiveness and productiveness of a particular product or service. Stream logging is achieved with minimum cost using transaction based model over a distribu...
