Resource constrained project scheduling problem (RCPSP) is mainly investigated with the objective of either minimizing project makespan or maximizing project net present value. However, when material planning plays a key role in a project, the existing models cannot help determining material ordering plans to minimize material costs. In this paper, the RCPSP incorporated with the material order...

This section provides details for Section 4.4 of the paper. We consider the class of contests with intermittently-public information disclosure: the principal specifies a set of times at which the entire history of successes to date is publicly disclosed; at other times, there is no information disclosed. Formally, an intermittently-public disclosure policy is a sequence (Mt, μt)t∈[0,T ] where,...

An exact solution of a system of coupled di erential equations describing the dynamics of a special class of winner-take-all networks is given. From the solution two properties of the short-termmemory traces are derived: (1) information preservation and (2) a discrimination measure. These properties justify a biologically inspired fault tolerant extension of the network using di erentiating neu...

In six experiments, we tested four explanations for the better/worse-than-average effect (B/WTA) bymanipulating the number of items comprising the target or referent of direct comparison. A single-item target tended to be rated more extremely ...

The Weapon-Target Assignment (WTA) problem aims to assign a set of weapons number assets (targets), such that the expected value survived targets is minimized. WTA nonlinear combinatorial optimization known be NP-hard. This paper applies several existing techniques linearize problem. One linearization technique (Camm et al. in Oper Res 50(6):946–955, 2002) approximates terms via convex piecewis...

Stock options are usually sold in bundles of 100 units, and their price can be quoted either per unit or per bundle. In this paper, the effect of different methods of quoting financial asset prices on the subjective value of a contract was examined experimentally. In particular, we examined differences in subjects’ Willingness-To-Pay (WTP) and Willingness-ToAccept (WTA) for financial assets dep...

Embodied autonomous agents are systems that inhabit dynamic, unpredictable environments in which they try to satisfy a set of time-dependent goals or motivations in order to survive. One of the problems that this implies is action selection, the task of resolving conflicts between competing behavioral alternatives. We present an experimental comparison of two action selection mechanisms (ASM), ...

The major problem that has prevented practical application of analog neuro-LSIs has been poor accuracy due to fluctuating analog device characteristics inherent in each device as a result of manufacturing. This paper proposes a dynamic control architecture that allows analog silicon neural networks to compensate for the fluctuating device characteristics and adapt to a change in input DC level....

Operating rooms have become the most important areas in hospitals because of the scarcity and cost of resources. The present study investigates operating room scheduling and rescheduling considering the priority of surgical patients in a specialized hospital. The ultimate purpose of scheduling is to minimize patient waiting time, surgeon idle time between surgeries, and penalties for deviations...

In this paper, an efficient extension of network simplex algorithm is presented. In static scheduling problem, where there is no change in situation, the challenge is that the large problems can be solved in a short time. In this paper, the Static Scheduling problem of Automated Guided Vehicles in container terminal is solved by Network Simplex Algorithm (NSA) and NSA+, which extended the stand...
