This paper considers a deteriorated multi-item economic order quantity (EOQ) problem, which has been studied in literature, but the algorithms used in the literature are limited. In this paper, we explore the optimal policy of this inventory problem by analyzing the structural properties of the model, and introduce a simple algorithm for solving the optimal solution to this problem. Numerical r...

The aim of this study was to undertake research on the building an active learning physical course that can improve problem-solving ability college students majoring in education. applied a quasi-experimental design, and participants were 60 Chinese students. experimental class consisted 30 students, who subjected methods for 8 weeks, totaling 32 hours, control without intervention other Proble...

We consider the simultaneous seat-inventory control of a set of parallel flights between a common origin and destination with dynamic customer choice among the flights. We formulate the problem as an extension of the classic multiperiod, single-flight “block demand” revenue management model. The resulting Markov decision process is quite complex, owing to its multidimensional state space and th...

OBJECTIVE To examine the effectiveness of an individualized problem-solving intervention delivered in videoconferencing sessions with family caregivers of persons living with a spinal cord injury (SCI) and possible contagion effects on care recipients. DESIGN Family caregivers were randomly assigned to an education-only control group or an intervention group in which participants received pro...

OBJECTIVE: To determine the percentage of family caregivers of persons with spinal cord injury (SCI) with probable depression and to test the hypothesis that dysfunctional problem-solving abilities would be significantly predictive of risk status after taking into account important demographic characteristics and caregiver health. DESIGN: Correlational and logistic regression analyses of data c...

background achievement in university education may be related to one’s emotional intelligent (ei) as well as his/her social skills and emotional control. therefore, it is also probable that the ei be associated with academic and occupational achievement in medical students. objectives the aim of this study was evaluation of the relation between ei and academic achievement of students working in...
