The objective of this study is to improve the efficiency emergency departments (ED) by decreasing overcrowding and patient waiting times. A hybrid methodology composed a combination lean techniques discrete event simulation models was followed. Value stream mapping (VSM) used as technique with aid ED staff. After obtaining future state map ED, two were developed. By reviewing each triage process, suggestions proposed changes incorporated into map. There five active process changes, reducing...

The background of sustainability is summed up by three words: Planet, People, and Profit. 3Ps require multi-objective research. This study analyzes the evaluation process optimization. Since it highly critical for decision makers to understand results models, Data Envelopment Analysis (DEA) approach used put Pareto-optimal model in an order analyze them. A case a reverse supply chain with four objectives namely economic, social, environmental legal taken into consideration. Results DEA...

Technological advances enable new business models that adopt the multiple lifecycle approach to design, manufacture and use of products. The Internet Things (IoT) paradigm can facilitate implementing Product Service Systems (PSS) model achieve Circular Economy through closed-loop material flow. Implementing PSS in IoT-enabled environments will require a supply chain network design. implementation requires more complex design reverse logistics operations reuse, remanufacture recycle options...

Traditional business models are generally sell-oriented, and Product Service Systems (PSS) often focus only on one lifecycle, limiting the prospects for enhancing triple bottom line benefits (TBL). Technological advances enabled through Internet of Things (IoT) paradigm can facilitate sustainability by implementing novel models. In this research we propose a 'Lease-First, Then-Sell' (LFTS) model adopting multiple lifecycle approach to design, manufacture use products. Simulation is used...

Sustainable innovations need more partnerships than available within the boundaries of an organization. Cooperation with research organizations, public institutions, nongovernmental intermediary organizations and other pressure groups as external actors for sustainable innovation play important role in organizational performance. Some factors such knowledge management, learning, culture influence this relationship internal factors. There has not been a comprehensive conceptual model that...

The Triple-bottom-line concept suggests that firms must consider the environmental and social impacts of their decisions, beside economic aspects. Hence, sustainability firms’ operations can be reached. purpose this study is to develop a bi-objective, multi-product multi-period mixed-integer model for planning electrical-electronic waste (WEEE) recovery facilities, by considering (workforce) constraints. Main objective minimization net recycling logistics costs offset profit earned recovered...

Üretim ortamının dinamik yapısı planlanmayı güçleştirmektedir. Gelişen teknoloji ile birlikte dijital ikiz, üretim süreçlerine etkin çözümler sunabilmek amacıyla artan bir şekilde kullanılmaya başlanmıştır. Bu çalışmada, kitlesel imalat sistemlerinde üretimin planlanması simülasyon temelli ikiz çizelgeleme modeli önerilmiştir. Böylece çözümü zor olan problemlerine yenilikçi ve uygulanabilir yaklaşım önerilmesi amaçlanmıştır. hattının kopyası gerçek zamanlı veri entegre edilmiş model,...

Construction is a complex process involving many parties with different responsibilities. Although the supplies made by all are closely related, VAT treatment of individual transactions must be assessed separately. Cross-border construction activities become even more complicated and may also give rise to fixed establishments. In this article, author discusses aspects projects under German law, gives number examples reflecting issues that arise for building contractors.

The popularity of the platform business model is on rise. Six ten most valuable companies in world derive much their value from multisided platforms. This article examines platforms as models and outlines some major indirect tax risks which operators are exposed to European Union.
