In this paper, a dynamic model is presented for production networks with a potentially large number of autonomous work systems, each having local capacity control. The model allows fundamental dynamic properties to be predicted using control-theoretic methods, together with the response of variables such as work-in-progress and lead-time for the network and its individual work systems. This is ...

Medium-term sales and operations as well as medium to short-term production planning in customer order driven production processes are performed using a cascading planning process. A lack of coordination and feedback between different planning phases causes problems with a negative effect on costs in production that originate from unfeasible production programs. Based on a system for the classi...

Limp materials like textiles, leather, porous tissues, meat and fish fillets do represent challenges in automation. A universal gripping principle that is usable for all these materials is not known. This paper describes a new gripping principle based on a novel Coanda effect ejector meeting these challenges. This ejector allows the construction of a slim, plate-shaped vacuum gripper with multi...

Modern manufacturing systems are characterized by numerous interacting machine tools each with sophisticated maintenance. In order to be competitive, it is possible to reduce the system downtime by applying sensorless automated condition monitoring (SACM). This paper presents newly developed and tested SACM-algorithms based only on signals which are available in position controlled drives such ...

A new Co-platforming methodology is introduced for mapping product features platform and corresponding manufacturing system machines platform. A cluster of platform and non-platform system machines are derived using matrix formulation and manipulation. The objective of Coplatforming is to establish the mapping between platforms of products and manufacturing machines for use in synthesizing syst...

This paper seeks to explore the aspects of being made homeless or internally displaced person (IDP) and how team attempted assess this. The 10 psychological researchers statisticians spent a day at five camps in four locations within Kegalle, Sri Lanka. languages are Tamil, English, Sinhalese. aim find out if depression, anxiety, trauma symptoms evident child, adolescents, adults categories, 3 ...
