abstract this author introduces the concept of stepwise strategy approach (ssa) for dealing with a number of problems arises in the current age of technology. this new idea is combined with the knowledge of grey theory for adding flexibility to decision making process. grey theory is useful for grasping the ambiguity exists in the utilized information and the fuzziness appears in the human judg...

We consider a size-structured population model with discontinuous reproduction and feedback through the environmental variable \substrate". The model admits solutions with nitely many cohorts and in that case the problem is described by a system of ODEs involving a bifurcation parameter. Existence of nontrivial periodic n-cohort solutions is investigated. Moreover, we discuss the question wheth...

This paper presents a critique of the normative, buyer-supplier literature and in addition suggests that the more empirically-based literature needs to expand its scope of attention beyond its traditional confines of attention. Four main deficiencies are identified within much of the existing buyer-supplier literature. Firstly, collaborative buyer-supplier theories fail to discriminate sufficie...

This is an incomplete draft of a paper that will examine the competitive tension that arises when banks which compete for deposits provide “interconnecting” payment services to each other’s depositors. This draft presents a basic theoretical model and discusses some of the analysis that can be carried out and issues that can be addressed with the model. 1 This work was undertaken while the auth...

The paper surveys theories of the intertemporal allocation of funds through demand deposits and anonymous markets, ...rst separately and then in an integrated model. It reviews some work on the role of market frictions and asset characteristics, and suggests that the interplay between these two is crucial in explaining the observed coexistence of demand deposits and anonymous markets. JEL class...

Although their importance in service operations is widely acknowledged in services marketing literature, the place and role of customers in organizational theories remain unclear. In particular, the way customers may influence the firm’s intra-organizational coordination has received little attention. By combining services marketing and intra-organizational coordination theories, this paper con...

This paper considers a graph-oriented, nonprocedural, development environment where new composite programs are constructed by coupling a collection of existing component programs, each of whose interface is defined by a fixed number of input ports and output ports. When the coupling graph is cyclic there is the possibility of a deadlock. The intent of this paper is to present a system that perm...

We analyze and compare geometrical theories based on mereology (mereogeometries). Most theories in this area lack in formalization, and this prevents any systematic logical analysis. To overcome this problem, we concentrate on specific interpretations for the primitives and use them to isolate comparable models for each theory. Relying on the chosen interpretations, we introduce the notion of e...
