Current major roadmapping efforts have all clearly underlined that true industrial sustainability will require far higher levels of systems’ autonomy and adaptability. In accordance with these recommendations, the Evolvable Production Systems (EPS) has aimed at developing such technological solutions and support mechanisms. Since its inception in 2002 as a next generation of production systems,...

Three growth models were used to examine the effects of prenatal exposure to aspirin on the postnatal development of brain parts. A total of 60 pregnant rats which were divided into three experimental groups and a control group were exposed to aspirin doses of 12.5, 25, 37.5 mg/kg, and distilled water, respectively. The brain parts of 200 rat pups starting from the first week after birth until ...

3D printing services are appearing, allowing consumers or businesses to order custom parts for delivery within a quoted lead-time, regardless of design specification. The manufacturer’s problem is to ensure that customers receive their goods on time, while capacity costs (including overtime costs) are kept low. We introduce a performance measure called the service rate, analogous to the fill ra...

Implementation of complex discrete event manufacturing systems can be considerably simplified by use of general reusable software modules, representing the physical components. At the same time, construction of the control system can be facilitated by use of formal methods for automatic generation of the control laws. These two aspects can be joined into a general concept with object oriented m...

Studies of bruises, as detected on carcasses at the slaughterhouse, may provide useful information about the traumatic situations the animals endure during the pre-slaughter period. In this paper, we review scientific data on the prevalence, risk factors and estimation of the age of bruises in beef cattle. Risk factors such as animal characteristics, transport conditions, stocking density, live...

This paper presents a simple algebraic approach for deriving the optimal lot size for economic production quantity (EPQ) model with rework process. Conventional methods for solving lot size problems are by using differential calculus on the long-run average production-inventory cost function with the need to prove optimality first. A few recent articles proposed the algebraic approach to the so...

T article proposes a supporting framework for the implementation of the material control system POLCA (paired-cell overlapping loops of cards with authorization). The POLCA system is particularly appropriate for environments that involve highly variable demand and large product variety, which force small batch (or even one-of-a-kind) production. We propose a load-based version of the POLCA cont...

In the classical inventory models, the common unrealistic assumption is that all the items produced are of good quality in nature. However, in realistic environment, it can be observed that there may be some defective items in an ordered lot. These items are usually picked up during the screening process and are sold as a single lot at the end of screening process. Further, it is tacitly assume...

The economic order quantity (EOQ) and the economic production quantity (EPQ) are well-known and commonly used inventory control techniques. The standard results are easy to apply but are based on a number of unrealistic assumptions. One of the assumption is that the demand is normally distributed in any interval. In several practical cases the assumption about independence of successive demands...

The well-established quarter car representation is used to investigate the design of an active suspension system for a racing car. The work presented is from both a practical and theoretical study. The experimental open-loop and passive responses of the suspension system are used to validate the model and estimate the level of damping within the system. A cascade control structure is used, cons...
