This simulation research assesses the effect of a reliability-based preventive maintenance approach to system performance for considering job shop scheduling problems with sequence-dependent setup time (SDST). Two types of reliability-based maintenance approaches are considered, i.e., reliability-centered preventive maintenance (RCPM) and a reliability-centered periodic preventive maintenance approach (RCPPM). The shop comprises 10 different machines and six job types. Six scheduling and two energy-oriented performance measures (Pms) are considered for evaluating the system’s performance. Results reveal that lower levels of reliability, namely, 0.74, 0.78, and 0.82 recommended for mean flow time, makespan, average operation energy consumption, average idle energy consumption, and total setups Pms. A 0.74 level of reliability is recommended for mean tardiness and the number of tardy jobs Pms for the RCPM approach. RCPPM approach provides the best system Pms by mean flow time, makespan, mean tardiness, average operation energy consumption, average idle energy consumption, and the number of tardy jobs when maintenance time is 5% of operation time. In contrast, mean setup, and total setups Pms are independent of maintenance time. Both approaches get compared, and its statistical analysis shows that if maintenance time is 15% or more than 15% of the operation time, the RCPM method is recommended. If maintenance time is 10% or less than 10% of the operation time, maintenance planning is recommended using the RCPPM approach. Considering real-time scheduling work with the environmental aspect represents the novelty of the present study.","PeriodicalId":53436,"journal":{"name":"Smart Science","volume":"9 1","pages":"283 - 304"},"PeriodicalIF":2.3,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23080477.2021.1938502","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46536065","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}

In general, oxides of nitrogen, total unburned hydrocarbon, carbon monoxide, carbon dioxide, and soot particles are the most significant emissions from gas-turbine combustion systems. In order to reduce these emissions, fuels derived from bio-origin are being increasingly used for gas-turbine combustion. Since aviation accounts for more than 5% of anthropogenic emissions, and also due to increasing pressure from governments across the globe for emission reduction, it is important to investigate pathways to reduce aviation-generated emissions. We, therefore, propose the use of Jatropha-based bio-derived synthetic paraffinic kerosene (SPK) blended with aviation turbine fuel (ATF)-Jet A1, and experimentally investigate the emission characteristics within a laboratory-scale gas-turbine combustor from proposed fuel blends. The investigation is done for two different operating conditions: operating condition 1 (OC1) and operating condition 2 (OC2). The influence of emission characteristics of the two biofuel blends, namely BF-II and BF-IV, are analyzed and compared with that of neat ATF-Jet A1. A substantial reduction of 33.5% in THC, 20% in CO, 42% in soot and increase of 40% in NO x and 28.7% in CO2 emissions are evident for BF-II fuel in comparison to ATF with OC1. However, at OC2, these emission reductions are less with increased NO x emissions of 50.2% in comparison to that of ATF. In addition, for the fuel BF-IV, there have been reductions of 57.2% THC, 33.3% CO, 67.1% soot and increase of 49.4% NO x and 43.9% CO2 emissions as compared with ATF at OC1. Also THC, CO, soot, and CO2 emissions are reduced considerably with increased NO x emissions for BF-IV fuel at OC2.
