Purpose The purpose of this study is to provide a model for evaluating, prioritizing and allocating orders suppliers in the supply chain mega-projects. Design/methodology/approach By using an integrated (based on fuzzy analytic network process), are selected appropriate amounts allocated them Initially, hierarchical research method was introduced. Then, results reliability validity analysis mea...

In this paper we investigate the problem of simultaneously allocating orders and mobile storage racks to static pickers. Here are allocated pickers enable them pick all products for that have been them. Problems type considered here arise in facilities operating as robotic fulfilment systems. We present a formulation an integer program discuss complexity problem. two heuristics (matheuristics) ...

When ejaculates are costly to produce, males are expected to allocate their ejaculate resources over successive matings in a manner that optimizes their reproductive success and this may have important consequences for their mates. In seed beetles (Coleoptera; Bruchidae), ejaculates vary in size across species from weighing less than 1%, up to as much as 8%, of male body weight. Ejaculates cont...

In this paper we present a set of laboratory experiments that investigate how human subjects solve the two-class capacity allocation revenue management problem. The two-class problem is the simplest possible revenue management problem, that is a fundamental building block for a family of complex and sophisticated RM problems. We study the capacity allocation problem with ordered and unordered a...

Economic regulation is characterized as (1) an effort by special interests to influence the allocation of property rights, in (2) a continuous path-dependent spontaneous evolution (as apposed to a static equilibrium), driven by (3) market, political, and bureaucratic entrepreneurship in an ongoing discovery process. The implications of the model are illustrated by an examination of the evolutio...

The Myers and Read capital allocation formula is an important new actuarial result. In this paper, we give an overview of the Myers and Read result, explain its significance to actuaries, and provide a simple proof. Then we explain the assumption the allocation formula makes on the underlying families of loss distributions as expected losses by-line vary. We show that this assumption does not h...
