Inventory management seeks to improve manufacturing by contracting inventory costs in a similar fashion raise efficiency and profit. One approach is develop models according actual production systems. Furthermore, governmental policies many countries impose regulations on firms fulfill the growing demand for reduction carbon emissions. Warm-up familiar concept industrial applications. It allows...
To explore the psychological and behavioral characteristics of severe internet addicts. Methods: 30 severe internet game addicts (aged from 16~25 years) and 43 non-addicts participated in the investigation. Measures included Internet Addiction Scale, Eysenck Personality Questionnaire (EPQ), Social Support Questionnaire, Life Purpose Scale and Sensation Seeking Scale. Results: Internet addicts g...
In two studies, we used the Ethics Position Questionnaire (EPQ) to investigate the relationship between individual differences in moral philosophy, involvement in the animal rights movement, and attitudes toward the treatment of animals. In the first, 600 animal rights activists attending a national demonstration and 266 nonactivist college students were given the EPQ. Analysis of the returns...
Today, “Sustainable production” has attracted a great deal of interest by academic researchers and practitioners due to the raising environmental and social concerns. Sustainable EPQ model has been developed as a result of this interest and also necessity. This paper develops a novel sustainable EPQ (SEPQ) model under partial backordering consideration. The model converts all emission variation...
Ovarian cancer is the deadliest gynecological malignancy in women, and fifth leading cause of death. Despite advances made in chemotherapy and surgery, the average time of clinical remission is approximately 2 years and the 5-year survival rate is 45%. Thus, there is an urgent need for the development of a novel therapeutic approach to ovarian cancer treatment. We investigated the effect of a s...
the traditional economic production quantity (epq) model assumes that during the production process no imperfect item is produced. but in the real production system, due to imperfect production process or other factors, imperfect quality items may be produced. furthermore, it is well-known that the total production-inventory costs can be reduced by reworking the imperfect quality items produced...
This study proposes a two-phase, algebraic approach to resolve the rotation cycle time and number of shipments for a multi-item, economic production quantity (EPQ) model with a random defective rate. A conventional method for solving a multi-item EPQ model is to use differential calculus and Hessian matrix equations on system cost function to prove convexity first and then derive an optimal pro...
