a r t i c l e i n f o JEL classification: C02 M11 C44 C61 Keywords: Multi-item production system Rotation cycle time Multi-delivery Economic production quantity model Scrap Vendor–buyer integrated system This paper addresses the joint determination of a rotation cycle time and number of shipments for a multi-item economic production quantity (EPQ) model with random defective rate. The classic E...

This study set out to re-examine the predictors of self-reported trait happiness as measured by the Oxford Happiness Inventory (OHI) as well as the predictors of various happiness types proposed by Morris (2004). In all, 120 Cypriot participants completed the 4 questionnaires: OHI, Eysenck Personality Questionnaire (EPQ), Trait Emotional Intelligence Questionnaire (TEIQue-SF), and Morris Multip...

This study reports the results of a biometrical genetical analysis of scores on a personality inventory (The Eysenck Personality Questionnaire, or EPQ), which purports to measure psychoticism, neuroticism, extraversion and dissimulation (Lie Scale). The subjects were 544 pairs of twins, from the Maudsley Twin Register. The purpose of the study was to test the applicability of various genotypeen...

A two warehouse production inventory model for deteriorating items is explored in an inflation induced demand and partial backlogging under the effect of learning on set-up cost. Holding cost is treated as a linear function of time and production rate is taken as a linear combination of demand and on-hand inventory. A finite planning horizon inventory problem having two separate warehouses, one...

Goldberg s (2001) IPIP Big-Five personality factor markers currently lack validating evidence. The structure of the 50-item IPIP was examined in three different adult samples (total N = 906), in each case justifying a 5-factor solution, with only minor discrepancies. Age differences were comparable to previous findings using other inventories. One sample (N = 207) also completed two further per...

this paper considers the economic lot scheduling problem, that is, the problem of scheduling several products on a single facility so as to minimize holding and setup costs. combination of frequency and timing as well as production quantity make this problem np-hard. a heuristic is developed to obtain a good solution to elsp. the proposed heuristic makes use of the simulated annealing technique...

This article considers a production system in which ‘‘m’’ identical machines produce nonidentical products at production rates. Products made by each machine are on the other hand consumed at a specific demand rate. Machines may be affected by unwanted breakdowns. Machines break down according to a Poisson distribution with equal rates and the failed machines are sent to maintenance center for ...

Order processing and inventory management are critical to costs. Therefore, this research aims reduce cost lead time for case study construction material retailer. The objectives 1) the order of retailer; 2) analysis techniques in decision making determine appropriate quantity. 30 employees interviewed collecting data a company raw from January – December, 2021 is used as data. ABC EOQ calculat...

This paper studies optimal production subsidy in a mixed duopoly with separation between ownership and management. Although many existing literature shows that the first best production allocation is achieved under several economic environments (so-called irrelevance result), we find that this result holds in the following two cases. (1) The owners simultaneously/sequentially decide their sales...

A manufacturing inventory model with shortages with carrying cost, shortage cost, setup cost and demand quantity as imprecise numbers, instead of real numbers, namely interval number is considered here. First, a brief survey of the existing works on comparing and ranking any two interval numbers on the real line is presented. A common algorithm for the optimum production quantity (Economic lot-...
