The object of the study is process functioning enterprises grain product subcomplex. In course study, problem growth rate and peculiarities subcomplex were solved. An assessment was carried out Republic Kazakhstan using mathematical modeling, for which a methodology has been developed that allows considering factors with heterogeneous metric, includes following steps: 1) index analysis twenty-o...

In this paper, the researchers have proposed a multi-dimensional knapsack model for project capital budgeting problem in uncertain situation which has been modeled through fuzzy sets. The optimistic and pessimistic situations were considered and associated deterministic models were yielded. Numerical example has been supplied toillustrate the performance of proposed model. The results were prom...

The proliferation of preferential trading agreements (PTAs) in different regions of the world has been a significant development over the last two decades or so. South Asian countries are slowly moving towards a South Asia Free Trade Area (SAFTA) in recent years. The desirability of SAFTA has been questioned by some observers recently. Do necessary conditions exist for a successful PTA in South...

Implementing a concurrent data structure typically begins with defining its sequential specification. However, when used as is, a nontrivial sequential data structure, such as a linked list, a search tree, or a hash table, may expose incorrect behavior: lost updates, inconsistent responses, etc. To ensure correctness, portions of the sequential code operating on the shared data must be “protect...

Our survival and wellness require a balance between optimism and pessimism. Undue pessimism makes life miserable; however, excessive optimism can lead to dangerously risky behaviors. A review and synthesis of the literature on the neurophysiology subserving these two worldviews suggests that optimism and pessimism are differentially associated with the two cerebral hemispheres. High self-esteem...

In a distributed system some or all of the data items are replicated and stored at separate sites. This increases the availability of these items and it is then possible to complete transactions faster than in a single site system. However, the concurrent processing of transactions at separate sites can generate inconsistencies in the stored information. Several replica control techniques have ...

A pessimistic consistency control algorithm for replicated les which achieves high availability. of replicated objects: A technique and its eden A majority consensus approach to concurrency control for multiple copy databases.

To address the adaptive value of optimism/pessimism an operational definition is required. I define a behavioural decision as relatively optimistic if it is consistent with the animal having either, a higher expectation of reward, or a lower expectation of punishment (threat), than the same animal in a different state (or a different animal). Pessimism is the inverse of optimism. Such relative ...

We prove that under mild conditions individually rational Pareto optima will exist even in presence of non-convex preferences. We consider decision makers dealing with a countable flow of payoffs or choosing among financial assets whose outcomes depend on the realization of a countable set of states of the world. Our conditions for the existence of Pareto optima can be interpreted as a requirem...
