Business Process Management Systems (BPMS) is a complex information system that provides designing, administrating, and improving the business processes. Task allocation to human resources is one of the most important issues which should be managed more efficiently in BPMS. Task allocation algorithms are defined in order to meet the various policies of organizations. The most important of these...

A great number of models have been proposed to investigate the deterioration inventory. However, most of models assume that a fixed physical quantity of items deteriorates over time, the quality of items does not decay before their expiration dates. In practice, the quality and physical quantity of many products, including fresh produce and foods, often deteriorate over time. The quality of an ...

In recent researches, vendor managed inventory (VMI) policy is rarely considered for deteriorating items.   This study considered the supply chain partner’s collaboration via a VMI system and provided an EOQ model for a two-level supply chain (single supplier - single retailer) to examine the inventory management proceedings for VMI and non-VMI supply chains. By a new approach in modeling, the ...

This paper addresses some single-machine scheduling problems with past-sequence-dependent (p-s-d) delivery times and deteriorating jobs. By the past-sequence-dependent (p-s-d) delivery times, we mean that the delivery time of any job is proportional to the job’s waiting time. It is assumed that the deterioration process reflects a increase in the process time as a function of the job’s starting...

  In this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. In this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. It is observed that the pumping power of nanofluid flowing and the maximum temperatur...

In order to evaluate the reliability of turbine blades over a certain time period, a time-dependent reliability analysis model is developed in this paper for turbine blades in extreme wind loading. The extreme wind loading over a certain return period and the deterioration of the blade material are considered to investigate the time influence on the reliability of turbine blades. Only failure i...

Circuit aging refers to the deterioration of circuit performance over time. All portions of a System-on-Chip (SoC), analog, digital logic, and memory, are affected by aging. In this survey, three main aging mechanisms will be introduced: Bias Temperature Instability(BTI), Time Dependent Dielectirc Breakdown(TDDB), Hot Carrier Injection(HCI). This survey also introduces a concept of circuit fail...

Wax deposition phenomenon changes the rheological behavior of waxy crude oil completely. In the current work, the rheological time-dependent and time-independent behaviors of waxy crude oil samples are studied and flow curve and compliance function are measured for the oil samples with various wax contents at different temperatures. A decrease in temperature and an increase in wax content lead ...
