A considerable problem in competitive trade world is choosing the best supply chain. As a result in much more serious circumstances of competitions looking for the best supplier for manufacturing, for preparing raw material, is very significant. Meantime suppliers have different scenarios to be fulfilled, such as changing selection variables like lead-time, transportation cost and transportatio...

This paper is a 10-year review (2003-2012) of aircraft-assisted pilot suicides and is a follow up to our previous 1993-2002 review. From 2003-2012, there were 2,758 fatal aviation accidents; 8 were aircraft-assisted suicides (intentional crashing of aircraft). This is half of what we found in our previous 10-year review. All pilots involved in these suicides were male (median age 46, range 21-6...

In this research, the removal of lead from the aqueous solution was investigated using natural nontoxic zeolite (clinoptilolite) as a low-cost adsorbent in order to reduce human exposure to it. The clinoptilolite zeolite obtained from the Semnan area was characterized by X-ray diffraction pattern, FTIR spectroscopy and scanning electron microscopy (SEM). The central composite design (CCD) defin...

PATIENTS expect and deserve safe, highquality healthcare that is free from preventable harmful events. In the United States, 247 people die every day as a result of a healthcare-associated infection.1 This is equivalent to a Boeing 767 aircraft crashing daily. Another staggering statistic is that nearly 100 000 people enter a hospital and die from an infection they acquired while receiving trea...

Analyzing the executions of a buggy software program is essentially a data mining process. Although many interesting methods have been developed to trace crashing bugs (such as memory violation and core dumps), it is still difficult to analyze noncrashing bugs (such as logical errors). In this paper, we develop a novel method to classify the structured traces of program executions using softwar...

The authors have been developing the automatic scheduling systems for software development project, which deliver scheduling and worker assignment. Their earlier works were designed to draw on crashing and fast tracking to produce countermeasure plans against process delay. However, process delay can be recovered not only by crashing or fast tracking but also by using holiday works. Their earli...

This paper is in search of designing the cellular manufacturing systems (CMSs) under dynamic and flexible environment. CM is proper for small-to-medium lot production environment that helps the companies to produce variable kind of productions with at least scraps. The most important benefits of CM are decline in material handling, reduction in work-in-process, reduction in set-up time, increme...

We consider an age-replacement model with minimal repair based on a cumulative repair cost limit and random lead time for replacement delivery. A cumulative repair cost limit policy uses information about a system's entire repair cost history to decide whether the system is repaired or replaced; a random lead time models delay in delivery of a replacement once it is ordered. A general cost mode...
