Jit Production

While firms are operating in a global competitive environment, they are subjected to changes because of the increased competitiveness and developed technologies. Therefore, this transformation process forces to produce with just-in-time production and low cost products or services and leads to customer satisfaction. Until today, competitive conditions, efficiency, productivity and quality of production, forced the firms to put more emphasis on production systems. Therefore, the firms are more interested in scientific analysis, planning and controlling of their production systems. As a result, one of the newest approaches is Just in Time (JIT) production system which emerged after WWII in Japan and aims to decrease the inventory cost and maximize the quality. The philosophy of this approach is to produce the necessary amount of production, when and where needed at the required quality.But JIT production system is weak in unclear species. For this purpose, the general and necessary solution is using fuzzy logic. In this paper we discussed about the simulation of an assembly line with 3 steps; firstly using Kanban production method, secondly non-using Kanban production method, and lastly using Kanban production method with fuzzy times. And also the comparisons of these steps will also be studied in this paper.

Cricoid pressure attempts to reduce the risk of aspiration during intubation. The technique is in routine use within the UK in line with current recommendations. Problems are often attributed to the application of an incorrect amount of force. Research has shown training to be limited in providing long-term benefit, with a skill retention period of <4 weeks. Using our previously created anatomically accurate comparatively low-cost cricoid pressure simulator, we have investigated the argument for cricoid pressure providers to perform just-in-time ‘self-calibration’ on a training device. The ‘Crikey Trainer’ device was used in four hospitals in South East England assessing 75 cricoid pressure providers. A structured interview examined: (1) cricoid pressure force before and after self-calibration; (2) associated skill knowledge; and (3) opinions on the device. 55% of participants successfully described cricoid ring location, 28% successfully described the force required. Difference between mean force and 30 Newton target improved in all groups after training (mean reduction 4.7N; p<0.0001). SD of measured force within each of the individual 30s tests reduced from an average of 3.0N (CI 2.62 to 3.36) to 2.09 (CI 1.75 to 2.42; p<0.0001). 97.3% of participants would consider using the device pre-Rapid Sequence Induction (RSI). We have developed an accurate cricoid pressure training device and improved cricoid pressure application force and variation. The data we and others have collected suggest that there is a place for regular pre-RSI self-calibration and that the majority of cricoid pressure providers would be receptive to it.

Abstract The Integrated Logistics Solutions Provider concept was introduced to support offshore drilling and production operations, save 20% on logistic costs, increase operational efficiency to achieve Just-in-Time deliveries and enable the upstream portfolio to focus on core competencies, thus seeking an One-stop contractor for logistics. This manuscript details how the logistics provider changed its operating model to an Integrated Logistics model, changed the status quo to become a competitive low-cost operating logistics provider and enabled operational and cost efficiency for Exploration and Production (E&P) customers. It also reflects on the technologies and commercial mechanisms used to drive the functioning of the operating model that meets the requirements of oil and gas operators.

Frequency Identification

With the benefits to improve productivity and reduce operation cost, RFID (Radio Frequency Identification) has recently seen a great increase in a wide variety of business information systems. However, the downside in business applications is the problem caused by data security and privacy. Enhancement without extra costs in RFID identification poses new challenges to privacy and security in RFID-driven just-in-time business information systems. In this paper, we propose an unilateral randomly authentication protocol on the basis of one-way hash function for low-cost RFID tags. We illustrate the whole operating procedure of the proposed protocol in a typical RFID system. Experimental results show that the proposed protocol has some security improvements in data consistency and can work against some attacks like eavesdropping and DoS, compared with several existing methods.

Organization Of Production

A study of evolution of the organization of production as a science has been conducted, beginning with the mechanized one and ending with lean production – from Fordism to Toyotism. The purpose of the research is to familiarize with the basic principles of organization of production in accordance with the concept of Toyotism and to provide recommendations that can serve as a basis for the formation of modern production systems in Ukraine. It is proved that Ukraine’s aspiration to integrate into European and world economic structures requires mastering of new principles of organization of production and business. In view of this, the research of the concept of business philosophy of Toyota Company, known in the world as Toyotism, was proposed. In authors’ opinion, the tools and methods for improving the quality of production, such as Just In Time (minimizing inventory), Kaizen (increasing the efficiency of using creative potential), Jidoka (exclusion of product defects), Heijunka (synchronization of production and management) are worth of particular attention. An important component of the concept is to identify and prevent the main types of losses (overproduction, waiting (time loss), unnecessary transportation and unrealized creativity of employees). In this context, the experience of using the 5S program, which includes a number of activities (steps) to eliminate losses, is of interest. The principles of Toyota, which underlie the formation of the Toyota Production System (TPS, the so-called Toyota House, or TPS-House), have been analyzed. Implementation of the main objectives of the TPS, including the high morale of workers and safety of work, excellent quality products at low cost and extremely short lead times, is especially relevant for domestic enterprises. It has been shown that introduction of Japanese management system does not guarantee the achievement of desired goals, although Japanese concepts and management methods are used throughout the world. A significant obstacle to this may be a cultural difference; so in the future it is expedient to study the activities of companies that have implemented the Japanese management system and have a stronger position in global markets.

Metastable beta titanium alloys have been known to have numerous advantages such as cold formability, high strength, good fracture resistance, deep hardenability, and cost effectiveness. Very high strength is obtainable by precipitation of the hexagonal alpha phase in a bcc beta matrix in these alloys. Precipitation hardening in the metastable beta alloys may also result from the formation of transition phases such as omega phase. Ti-15-3 (Ti-15V- 3Cr-3Al-3Sn) has been developed recently by TIMET and USAF for low cost sheet metal applications. The purpose of the present study was to examine the aging characteristics in this alloy.The composition of the as-received material is: 14.7 V, 3.14 Cr, 3.05 Al, 2.26 Sn, and 0.145 Fe. The beta transus temperature as determined by optical metallographic method was about 770°C. Specimen coupons were prepared from a mill-annealed 1.2 mm thick sheet, and solution treated at 827°C for 2 hr in argon, then water quenched. Aging was also done in argon at temperatures ranging from 316 to 616°C for various times.

Polyethylene is one of the most important plastics produced today because of its good physical properties, ease of fabrication and low cost. Studies to improve the properties of polyethylene are leading to an understanding of its crystalline morphology. Polyethylene crystallized by evaporation from dilute solutions consists of thin crystals called lamellae. The polyethylene molecules are parallel to the thickness of the lamellae and are folded since the thickness of the lamellae is much less than the molecular length. This lamellar texture persists in less perfect form in polyethylene crystallized from the melt.Morphological studies of melt crystallized polyethylene have been limited due to the difficulty of isolating the microstructure from the bulk specimen without destroying or deforming it.
