This paper presents issues and tradeoffs in attempting to achieve lean production by increasing productivity and reducing costs and waste while at the same time operating with resilience in the face of disruptions. A simple mathematical model of the operation of a production system is proposed, which incorporates two types of disruptive events: resource breakdowns and quality loss. The model is...

We evaluated abdominal adipose tissue leptin production during short-term fasting in nine lean [body mass index (BMI) 21 +/- 1 kg/m(2)] and nine upper body obese (BMI 36 +/- 1 kg/m(2)) women. Leptin kinetics were determined by arteriovenous balance across abdominal subcutaneous adipose tissue at 14 and 22 h of fasting. At 14 h of fasting, net leptin release from abdominal adipose tissue in obes...

This paper presents an application of 5S lean technology to a production facility. Due to increased demand, high product variety, and a push production system, the plant has suffered from excessive wastes, unorganized workstations, and unhealthy work environment. This has translated into increased production cost, frequent delays, and low workers morale. Under such conditions, it has become dif...

International markets driven forces are changing continuously, therefore companies need to gain a competitive edge in such markets. Improving the company's products, processes and practices is no longer auxiliary. Lean production is a production management philosophy that consolidates work tasks with minimum waste resulting in improved productivity. Lean production practices can be mapped into ...

Lean Production has proved itself a worthwhile production strategy in many distinct industries across all regions of the planet by achieving higher levels of production efficiency. Several authors identified that Lean inadvertently has had significant environmental gains. Such achievements are considered of special relevance in a global and highly competitive economy which is progressively both...

One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell’s r...

The lean approach is an idealizing improvement approach that has an enormous impact in the field of Operations Management. The approach is basically very process oriented and there was less attention first for planning and control, this being the profession of dealing with all kind of non-ideal manufacturing and supply-chain restrictions. During the last years, however, planning and control hav...

The Japanese automobile manufacturer invented Lean Production or Toyota Production System (TPS) which has been introduced and implemented in Swedish manufacturers for around 20 years (Dabhilkar, et al., 2005). Many studies discussed how it creates success in optimizing production process and quality. However, many researches show that the gap between culture become the main barrier in the proce...

Project management that solely focuses on the management of time, cost and quality cannot comprehensively ensure the satisfactory meeting of a customer’s needs. Project management performance with regard to this issue can be improved by enhancing project management’s ability to meet a customer’s needs. This paper introduces lean project management to address this concern. Lean project managemen...

OBJECTIVE To compare overweight and lean subjects with respect to thermogenesis and physiological insulation in response to mild cold and rewarming. RESEARCH METHODS AND PROCEDURES Ten overweight men (mean BMI, 29.2 +/- 2.8 kg/m(2)) and 10 lean men (mean BMI, 21.1 +/- 2.0 kg/m(2)) were exposed to cold air for 1 hour, followed by 1 hour of rewarming. Body composition was determined by hydroden...
