An imperfect production at the manufacturer and inspection process involving with Type I and II errors at the retailer are considered. We assume that the manufacturer gives products to the retailer in a number of equal-sized shipments. This model is formulated as a Stackelberg game in which the retailer retains a certain degree of autonomy by reserving the right to choose the retail price and the manufacturer determines replenishment frequency, replenishment quantity and wholesale price. The critical supply chain decision factors including the manufacturer’s wholesale price, the retailer’s price, shipment frequencies and number of shipments are determined maximizing the total profit of each member of the supply chain. A solution procedure is proposed to find the Stackelberg game equilibrium. The performance of the model is assessed by a numerical example. The numerical shows that it is more beneficial for both the manufacturer and the retailer when the demand is less price sensitive.","PeriodicalId":44022,"journal":{"name":"Engineering Review","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69598238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dwivedi","doi":"10.30765/er.1685","DOIUrl":"https://doi.org/10.30765/er.1685","url":null,"abstract":"To ensure higher reliability, it is necessary to identify the most prominent cause of failure. It was observed in multiple works that most of the researchers used failure mode and effect analysis (FMEA) and failure mode and effect criticality analysis (FMECA) but these approaches contain lots of hindrances. Alternatively, the MATRIX FMEA approach applied to identify the most prominent cause of failure and critical sub-component prone to that particular failure. The matrix FMEA developed for design engineers so that they can identify the potential cause of failures and design-out them in new product design. The central idea of this research is to apply this approach to maintenance, since the potential failure mode and the affected components were known. In most research, a single component such as a cylinder or turbocharger is used for analysis, but this research targets an entire machine. Multiple researchers also highlighted that the combination of non-destructive testing (NDT) provides better results instead of single NDT. Multiple researchers also highlighted the suitability of the analytical hierarchy process (AHP) and preference ranking organization method for enrichment evaluation (PROMETHEE) for decision making (DM). Therefore, this work covered firstly, a novel AMFMEA (AHP-Matrix FMEA) to identify the most critical component of particular machinery located in a heavy industrial setup and secondly, DM approach for combining NDTs. It was observed that the incorporation of AHP in Matrix-FMEA improved its analytical ability and reduced overall computation time. This work also provided the guideline with a detailed procedure for combining NDTs.","PeriodicalId":44022,"journal":{"name":"Engineering Review","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69598054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Normalization conducted at a temperature of 900 °C with a holding time of 30, 60, 90, 120, and 150 minutes, followed by cooling down to a room temperature by using an external air. Corrosion testing of normalized specimens was performed using seawater as a corrosive environment, -and specimens were also tested for microhardness to determine their mechanical properties. Then, these test specimens were compared with specimens that did not undergo normalization in terms of their microstructure, hardness, and other mechanical properties. The specimens were analyzed by using an Energy Dispersive X-ray (EDX) Spectroscopy to determine the microstructure grain boundary, chemical composition and microcracking of the metal specimens. The results showed that the base metal hardness of API 5L X65 steel pipe fluctuated and tended to decrease. The highest hardness was obtained in specimens without normalizing, and the lowest in normalizing specimens. The highest corrosion rate occurred in specimens without normalizing, and the lowest in specimens with normalizing. Typical corrosion results of seawater on APL 5L-65 pipe are cracking and pitting.","PeriodicalId":44022,"journal":{"name":"Engineering Review","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69597955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This PGT may be used for applications in which a negative transmission ratio in the range -3…-143 is required. In this case, the mechanical and dimensional properties of the PGT have been analyzed for nominal negative transmission ratios of -30 and -40. All possible combinations of simple component PGT ideal torque ratios providing those transmission ratios were obtained. Only the combinations providing the minimum radial dimensions of the PGT assembly were selected. Subsequent analysis has shown that the PGT radial dimensions will be minimized when the ratio of the reference diameters of the planetary unit ring gears is close to unity, meaning that the PGT casing will be cylindrical rather than stepped. This paper also provides an overview of the DVOBRZ software package used to synthesize the different gearbox layouts for the required transmission ratio, combined with a basic introduction to single speed two-carrier PGTs for better understanding. The DVOBRZ software was used to select all the acceptable gearboxes were selected from the set of generated PGTs according to the criteria of minimum dimensions and acceptable efficiency range. This set of PGTs was checked for kinematic feasibility and construction concepts were created for feasible layouts.","PeriodicalId":44022,"journal":{"name":"Engineering Review","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69598388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Panda","doi":"10.30765/er.1925","DOIUrl":"https://doi.org/10.30765/er.1925","url":null,"abstract":"Load frequency control (LFC) is a crucial feature of electric power systems to maintain a balance between power supply and load demand, thus avoiding a deviation of the grid frequency. The present work aims to implement an effective LFC scheme for a microgrid system consisting of a diesel generator (DEG), a wind turbine generator (WTG) and a battery storage system. Proportional-integral-double-derivative (PIDD) controllers are used to implement the proposed LFC scheme. The controller parameters are computed using an innovative hybrid teaching-learning-optimization differential-evaluation (hTLO-DE) algorithm. The main scope of the work lies in application of hTLO-DE optimized PIDD controllers in DEG-WTG-battery storage based MG system. The results obtained with PIDD controllers are compared with those obtained with the traditional PI and PID controllers. A critical analysis shows that the PIDD controller can provide better dynamic responses in terms of settling time and magnitude of oscillations compared to PI and PID controllers. The frequency responses of the system are studied under different scenarios of generation and load variations, which establishes the robustness of the proposed PIDD-based LFC scheme.","PeriodicalId":44022,"journal":{"name":"Engineering Review","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69598615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
