This paper presents a nonlinear mixed-integer programming model to minimize the stoppage cost of mixed-model assembly lines. Nowadays, most manufacturing firms employ this type of line due to the increasing varieties of products in their attempts to quickly respond to diversified customer demands.

This paper presents a new mathematical programming model for the bi-criteria mixed-model assembly line balancing problem in a just-in-time (JIT) production system. There is a set of criteria to judge sequences of the product mix in terms of the effective utilization of the system. The primary goal of this model is to minimize the setup cost and the stoppage assembly line cost, simultaneously. B...

[1] Ross ice streams supply over 90% of the ice volume flowing out of the Ross sector of the West Antarctic ice sheet (WAIS). Stoppage of Ice Stream C (ISC) ca. 150 years ago appears to have pushed this sector of WAIS from negative into positive mass balance [Joughin and Tulaczyk, 2002]. We propose an explanation for the unsteady behavior of ISC using a new numerical ice-stream model, which inc...

Having in view the statistical data calculated for 10 years, the total consumption of rolling mill rolls represents 0 785...0 8 kg/tone of rolled steel. Nationwide, the 5 million tones steel being rolled every year represents a consumption of 4000 tones rolls, worth 6 million euro/year, which imposes large research with an important economic and scientific impact [1-6] It is noticeable that app...

BACKGROUND the rise in life expectancy, together with age-related increase in the incidence of most cancers, has led to mounting interest in cancer screening in older people. In England, routine invitations stop and an 'opt-in' (individual request) process is available from ages 71 to 76 years for breast and colorectal screening respectively. Little is known about public attitudes towards age-s...

Early fault detection by using vibration monitoring devices could help industries to avoid sudden stoppage of the machine, thus reduces machine downtime and maintenance cost save time money. measurement are very useful for determining condition rotating elements its analysis. In this paper, experimental studies were performed predict misalignment faults in which is connected with simple rigid c...
