Imperfect quality items are unavoidable in an inventory system due to imperfect production process, natural disasters, damages, or many other reasons. The setup cost and production cycle time can be related in terms of process deterioration and learning and forgetting effects. Learning reduces production run length and setup cost, whereas deterioration and forgetting increases both. Keeping the...
We tested the idea that Psychoticism, a major personality dimension, is rooted in individual differences in dopamine functioning. To this end, we related the spontaneous eye blink rate (EBR), a marker of striatal dopaminergic activity, to scores in the Eysenck Personality Questionnaire Revised Short Scale (EPQ-RSS) in adult healthy subjects. The level of Psychoticism was indeed predicted by EBR...
The influence of sociability/impulsivity in caffeine-induced arousal effects was investigated in two separate experiments: Experiment 1 examined critical flicker/fusion frequency change scores (ACFFT) in 60 subjects; and Experiment 2 investigated procedural learning in 30 subjects. In the two experiments, subjects received either caffeine citrate (500 mg) or placebo. The pattern of results was ...
We have developed an order level inventory system for deteriorating items with demand rate as a ramp type function of time. The finite production rate is proportional to the demand rate and the deterioration rate is independent of time. The unit production cost is inversely proportional to the demand rate. The model with no shortages case is discussed considering that: (a) the demand rate is st...
In reality, a seller (e.g., a supplier or a manufacturer) frequently offers his/her buyers trade credit (e.g., permissible delay in payment). Trade credit reduces the buyer's holding cost of inventory and hence attracts new buyers who consider it to be a type of price reduction. On the other hand, granting trade credit also increases the seller's opportunity cost (i.e., the loss of capital oppo...
In this work, an integrated model of economic production quantity, economic design of an -control chart, and preventive maintenance are investigated under non-uniform quality control parameters. The effect on the expected total cost and quality control cost is investigated with three different assumptions of the quality control parameters. Using a tabu seach algorithm, the optimal values of qua...
The traditional method of determining the optimal Economic Manufacturing Quantity (EMQ) policy for an unreliable production system is the minimization of the expected cost per unit time in the steady state which does not consider the reliability of the system in true sense. The purpose of this article is to introduce an alternative criterion of optimality called cost effectiveness which takes i...
This paper derives a production model for the lot-size inventory system with finite production rate, taking into consideration the effect of decay and the condition of permissible delay in payments, in which the restrictive assumption of a permissible delay is relaxed to that at the end of the credit period, the retailer will make a partial payment on total purchasing cost to the supplier and p...
Physical risk taking activities can be classified along a continuum ranging from prosociality to antisociality, the risky sports being in an intermediate point of that hypothetical dimension. The present study was aimed at identifying the personality variables common to those who engage in physical risky activities, and those that differentiate among the groups along the continuum. The sample c...
Background and Objectives: Traditionally, depression among adolescents has been considered uncommon, with around 5% estimated to suffer from depressive disorder. The purpose is to investigate occurrence and psychological correlates for depressive symptoms in male and female high school adolescents in urban and rural settings. Methods: Participants were 1,069 high school students (response rate ...
