Manufacturing organizations always needs some ways to reduce production lead time, eliminate waste and increase quality to survive in today’s competitive world. Lean manufacturing is such a technique used by industries all over the world in past few decades. It consists of various tools and techniques to reduce waste and increase productivity. One of the major tools in lean manufacturing is Val...

an erosion hazard index methodology (ehim) was developed for assessing stream erosion. the index of stream erosion is designed as a management tool. assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. the assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. a ...

Value stream mapping is a lean tool which is used in lean manufacturing to find the flow of information and material, as a product it makes way through value stream. These envision tool helps to understand processes by using of stream lined work process. In these paper value stream maps of a process by using simulation is developed. By creating dynamic value stream maps makes it possible to ana...

BACKGROUND This paper presents the findings of a 13-month lean implementation in National Health Service (NHS) primary care health visiting services from May 2008 to June 2009. METHOD Lean was chosen for this study because of its reported success in other healthcare organisations. Value-stream mapping was utilised to map out essential tasks for the participating health visiting service. Stake...

Stream is re-interpreted in terms of a Lazy monad. Future is substituted for Lazy in the obtained construct, resulting in possible parallelization of any algorithm expressible as a Stream computation. The principle is tested against two example algorithms. Performance is evaluated, and a way to improve it briefly discussed.

This study applies lean production and radio frequency identification (RFID) technologies to improve the efficiency and effectiveness of supply chain management. In this study, a three-tier spare parts supply chain with inefficient transportation, storage and retrieval operations is investigated. Value Stream Mapping (VSM) is used to draw current state mapping and future state mapping (with lea...

R. Wolniak, B. Skotnicka-Zasadzien, Silesian University of Technology, Institute of Production Engineering, Zabrze, Poland Organizational innovation is an important activity affecting the productivity of the organization. This paper presents a method of lean management – the method of value stream mapping. On the basis of the literature we shows the main features of the method. For example, a s...

Sequential Monte Carlo (SMC) methods are powerful techniques for online filtering of nonlinear and non-Gaussian dynamic systems. Typically dynamic systems exhibit strong memory effects, i.e., future observations can reveal substantial information about the current state. Recently, the delayed-sample sampling method has been proposed in the context of mixture Kalman filter (MKF), which makes use...

A change in the stock value of a company is an important indicator of firm performance. Event studies, which look at abnormal stock price reactions to specific events or happenings that may impact a business's operations, represent a relatively new but fast growing research approach in the information systems field. Building on earlier literature reviews, in this paper we examine forty-six even...
