Small and medium size enterprises often encounter problems in managing and operating production system effectively and efficiently, which result in losing their competitive advantages. It is, therefore, essential to suggest applicable methods to solve these problems completely and inexpensively. Purposely, an application of work design and standardization process to rationalize manufacturing work station would be proposed. A case study at a furniture company is presented as an example. It aims to create a scientific workstation with standardized operations to help worker get more comfortable, and increase productivity, quality and safety. An implementation of proposed method at a workstation of a furniture company brings promising results. A new workstation is redesigned more effectively in terms of comfortableness, safety, and the productivity increasing 15%.

The Lean Kitchen is based on the Japanese TPS (Toyota Production System) system that increases productivity, efficiency and effectiveness within the kitchens. One of the principles of this philosophy is to identify the problem, optimizing resources to reduce waste, that is, lean manufacturing, in terms of eliminating bottlenecks and gaps. This article brings the theme of Lean Kitchen, to increase productivity, efficiency and effectiveness within the kitchens, as well as the concept of value, in terms of how much the customer is willing to pay. Therefore, the objective is to apply the lean concept within its outsourced industrial restaurants. Restaurants respond to variations in demands and varieties of service, however, as in any process, there are several problems that need to be meticulously detected in order to heal them. Literature based on Lean philosophy and the case study and metrics were used, such as: Visit to the Gemba reports; information collections; check-list application; problem identification; Brainstorming (team and leadership); Dynamics of engagement with team and leadership; visual communication application, feedback schedule with customers; Tools (5s; Pareto, Ishikawa, 5W2H; PDCA).

Abstract The goal of this paper is to help small and medium size enterprises (SMEs) to find operative competitive advantage. This paper introduces a new method which applies critical factor analysis, risk and opportunities analysis to measure and propose resource allocation for companies in couple of next years. this research shows Knowledge/Technology (K/T) Calculation effect on (Balanced) Critical Factor Index (CFIs) depending on the proportions allocated among the different technological levels (Basic, Core or Spearhead) for each attribute separately. Moreover it helps firms to take balance in resource allocation for each attribute in changing environments on the basis of different level of technology. This paper presents the ’first in the world’ case study on operative sustainable competitive advantage and corresponding risk levels by taking into account technology and knowledge effects for 7 SME companies

Major oil fi elds in Indonesia have been experiencing massive decline in production, accompanied by excessive sand production that is not benefi cial to the integrity of the production system. Sand production has been known to increase the potential of corrosion, reducing lifetime of well equipment, and also known to shut in wells completely due to sand buildup in wellbore. Progressive Cavity Pump has been proposed as a solution to withstand these complications, due to its nature that can handle many types of fl uids and even produced solid. The idea is then tested to a mature Alabaster fi eld where the majority of the wells have been shut in due to excessive sand problem and low productivity. It is worth nothing that after installing the PCP, production modeling indicates possibility of sustaining production through the application of PCP, where the production increases around 120 STB/ day. Although PCP has proven its effectiveness, it is important to note that auxiliary sand mitigation techniques is required to maintain facilities integrity after several years of production.

This paper discusses a digital twin-based approach for designing and redesigning flexible assembly systems. The digital twin allows modeling the parameters of the production system at different levels including assembly process, production station, and line level. The approach allows dynamically updating the digital twin in runtime, synthesizing data from multiple 2D–3D sensors in order to have up-to-date information about the actual production process. The model integrates both geometrical information and semantics. The model is used in combination with an artificial intelligence logic in order to derive alternative configurations of the production system. The overall approach is discussed with the help of a case study coming from the automotive industry. The case study introduces a production system integrating humans and autonomous mobile dual arm workers.

A new regulatory framework to support local quality and safety efforts in hospitals was introduced to the Norwegian healthcare system in 2017. This study aimed to investigate hospital managers’ perspectives on implementation efforts and the resulting work practices, to understand if, and how, the new Quality Improvement Regulation influenced quality and safety improvement activities.DesignThis article reports one study level (the perspectives of hospital managers), as part of a multilevel case study. Data were collected by interviews and analysed according to qualitative content analysis.SettingThree hospitals retrieved from two regional health trusts in Norway.Participants20 hospital managers or quality advisers selected from different levels of hospital organisations.ResultsFour themes were identified in response to the study aim: (1) adaptive capacity in hospital management and practice, (2) implementation efforts and challenges with quality improvement, (3) systemic changes and (4) the potential to learn. Recent structural and cultural changes to, and development of, quality improvement systems in hospitals were discovered (3). Participants however, revealed no change in their practice solely due to the new Quality Improvement Regulation (2). Findings indicated that hospital managers are legally responsible for quality improvement implementation and participants described several benefits with the new Quality Improvement Regulation (2). This related to adaptation and flexibility to local context, and clinical autonomy as an inevitable element in hospital practice (1). Trust and a safe work environment were described as key factors to achieve adverse event reporting and support learning processes (4).ConclusionsThis study suggests that a lack of time, competence and/or motivation, impacted hospitals’ implementation of quality improvement efforts. Hospital managers’ autonomy and adaptive capacity to tailor quality improvement efforts were key for the new Quality Improvement Regulation to have any relevant impact on hospital practice and for it to influence quality and safety improvement activities.

The SAR Doppler frequencies are directly related to the motion of the scatterers in the illuminated area and have already been used in marine applications to monitor moving water surfaces. Here we investigate the possibility of retrieving surface water velocity from SAR Doppler analysis in medium-size lakes. ENVISAT images of the test site (Lake Garda) are processed and the Doppler Centroid Anomaly technique is adopted. The resulting surface velocity maps are compared with the outputs of a hydrodynamic model specifically validated for the case study. Thermal images from MODIS Terra are used in support of the modeling results. The surface velocity retrieved from SAR is found to overestimate the numerical results and the existence of a bias is investigated. In marine applications, such bias is traditionally removed through Geophysical Model Functions (GMFs) by ascribing it to a fully developed wind waves spectrum. We found that such an assumption is not supported in our case study, due to the small-scale variations of topography and wind. The role of wind intensity and duration on the results from SAR is evaluated, and the inclusion of lake bathymetry and the SAR backscatter gradient is recommended for the future development of GMFs suitable for lake environments.
