Assembly line rebalancing is a problem companies are frequently confronted with as continuous changes in product features and volume demand caused by the volatility of modern markets result re-definition assembly tasks cycle time fluctuations. Consequently, managers forced to adjust balancing their lines order adapt new conditions while trying minimise both increases completion costs related task assignment. In particular, when modifications made balancing, incurred for operator training,...

The design of logistic distribution systems is one the most critical and strategic issues in industrial facility management. aim this study to develop apply innovative mixed integer programming optimization models manage dynamic (i.e. multi-period) multi-stage multi-commodity location allocation problems (LAP). LAP belong NP-hard complexity class decision problems, generic occurrence requires simultaneous determination number facilities (e.g. production plants, warehousing systems, centres),...

This article addresses the relationship between Public-Private Partnerships (PPP) and sustainability of public spending in smart hospitals. Smart (technological) hospitals represent long-termed investments where private players interact with banking institutions eventually patients, to satisfy a core welfare need. Characteristics are critically examined, together actors’ involvement flexible forms remuneration. Technology-driven so complicated that they may require sophisticated PPP. Public...

This paper deals with the production scheduling problem customer-driven demand substitution. We consider a manufacturing system in make-to-stock environment which is potentially able to produce large variety of product options (the so-called long-term assortment) but, for reasons capacity and operative limitations, only subset those can be available stock at same time short-term assortment). In such context, typical fields where high-variety strategies are applied, first-choice option...

The paper deals with the problem of assigning jobs to operators in contexts where are not fixed on a single position, but rotate, by travelling foot, between different stations. objective is jointly consider need for minimising operators' walking costs, expressed as both unproductive times and physiological ergonomic risk scheduled their combinations. A new optimisation-based methodology presented developing systematic procedure input data analysis an original mixed-integer linear...

This article deals with the analytical modeling of transfer lines consisting two machines decoupled by one finite buffer. The innovative contribution this work consists in representing a particular behavior that can be found number industrial applications, such as ceramics and electronics industries. Specifically, buffer significantly affects line's performance as, when it is accumulating or releasing material (i.e., machine operational other under repair), forces to slow down. Conversely,...

An increased interest towards environmental respect amongst consumers, managers and researchers is registered, owing both to changing sensitivity guidelines described in technical regulations. In this scenario, the European Union (EU) directives 2002/96/EC 2003/108/EC, controlling management of Wastes Electric Electronic Equipments (WEEE) are well-inserted. Companies producing (EEE) become responsible for end life steps their products. Hence, great efforts made optimise recovery networks...

This article focuses on analytical models of two-machine one-buffer Markov lines including waste production. The aim is to compute the probability producing good parts, referred as effective efficiency, when production related stoppages first machine. problem common in industrial fields where parts are generated by a continuous process; e.g., high-speed beverage packaging lines. Two innovative presented: WP-Basic Model extends model basic two-machine–one-buffer transfer line; WP-RP line with...

Abstract Modern market scenarios are imposing a radical change in the production concept, driving companies’ attention to customer satisfaction through increased product customization and quick response strategies maintain competitiveness. At same time, growing development of Industry 4.0 technologies made possible creation new manufacturing paradigms which an level autonomy is one key concepts consider. Taking advantage from recent around semi-heterarchical architecture, this work proposes...

Low cost automation and poka yoke philosophy assure good results when applied to manufacturing processes with a high incidence of human operators, low availability time for solution implementation expensive effects associated errors in executing operative procedures. Hence, their joint adoption is addressed order access the benefits they both guarantee. Specifically, this paper, case line heat exchangers studied. Operative tools are redesigned accordance principles. Furthermore, since...

In the paper, we introduce Special Issue entitled “New Project Financing and Eco-Efficiency Models for Investment Sustainability”, later present form contents of thematic issue.

This work is part of a research project aimed at developing bio-based binder, composed mainly polylactic acid (PLA), to produce Ti6Al4V feedstock suitable for use in MAM (Metal Additive Manufacturing) via mFFF (metal Fused Filament Fabrication), order manufacture titanium alloy specimen. While Bragaglia et al. the mechanical characteristics this sample were analyzed, aim used study compare mentioned process with one most processes aerospace applications, known as Selective Laser Sintering...

Given the relevance of stochastic modelling in supply chain analysis and advances queuing theory different subject fields (such as in-plant manufacturing systems), present paper deals with application a Bernoulli model to simple but representative (and frequently cited) case single-vendor single-buyer (s, S)-inventory policy, where maximum capacity S has be restored intermediate warehouse whenever inventory position reaches or drops below reorder point s. An analytical is presented which...
