Takt production has been of great interest in construction during the last few years. In this research, a case study was carried out to demonstrate how the scheduling of an apartment building renovation project that utilizes takt production can be done. Furthermore, the study defines what clarifications should be made into the existing takt production models in the context of apartment building renovation projects, and it also explains why. Based on the study, adhering to a uniform production rate is challenging in apartment renovation projects. Therefore, a total of five clarifications to existing takt production methods are suggested. (1) Production with short takt requires a highly detailed definition of tasks in order to avoid ambiguousness. (2) Some tasks carried out in takt areas may have to be excluded from takt production. (3) The sensitivity of a created takt schedule should be evaluated, and buffers should be added accordingly. (4) Emphasis must be put on coordinating takted and non-takted tasks. (5) Takt plan modification during production requires effective procedures, since there is little time to react.

Economic optimization of an oil and gas project is an obligation that has to be done to increase overall profi t, whether the fi eld is still economically feas ible or the fi eld has surpassed its economic limit. In this case, a marginal fi eld waschosen for the study. In this marginal fi eld EOR methods have been used to boost the production rate. However, a full scale EOR method might not be profi table due to the amount of resources that is required to do it. Alternatively, Huff and Puff method is an EOR technique that is reasonable in the scope of single well. The Huff and Puff method is an EOR method where a single well serves as both a producer and an injector. The technique of Huff and Puff: (1) The well isinjected with designed injection fl uid, (2) the well is shut to let the fl uid to soak in the reservoir for some time, and (3) the well is opened and reservoir fl uids are allowed to be produced. The injection fl uid (in this case, nano surfactant) is hypothesized to reduce interfacial tension between the oil and rock, thus improving the oil recovery. In this study, the application of Huff and Puff method using Nanoparticles (NPs) as the injected fl uid, as a method of improving oil recovery is presented in a case study of a fi eld in South Sumatra. The study resulted that said method yields an optimum Incremental Oil Production (IOP) in which the economic aspect gain more profi t, and therefore it is considered feasible to be applied in the fi eld.

Abstract Municipal solid waste (MSW) from Al-Karak city is monitored and characterized. The MSW is sorted into 14 different waste categories. In addition, the MSW is separated into several size fractions, followed by sorting and characterization. The average daily production rate of waste is 61.5 ton/day. The MSW generated per capita is estimated to be 0.55 kg/capita/day. The main input MSW comprised a modest proportion of organic content 38.8 %. Other combustible fractions are present in significant proportions, allowing the waste to be utilized for energy recovery. Refuse-derived fuels (RDFs) may be made from waste fractions > 100 mm and 50 – 100 mm.

Abstract To remain economical, mature offshore oil fields require unique, time-efficient and cost-efficient drilling and completion operations for each well. This paper is a case study of a rapid selection method for determining the operational process for each offshore oil well candidate and its application in the Zhaodong oilfield. In mature oilfields, maintaining production requires drilling and completing sidetrack wells. There are 3 key steps to rapidly selecting the most suitable drilling, completion and operational strategy for each well. First, review historical production data and operational costs to set production targets for each well. Second, evaluate the potential drilling and completion operations both technically and economically to achieve the target. Third, optimize the selected operations based on prior field application and production results. This process was applied with newly sidetracked wells in the Zhaodong oilfield. The wells were either completed using a multi-zone cased hole fracturing technique or an open hole completion technique, per the selection process. One candidate well completed with the multi-zone fracturing technique had a daily production rate of 134 tons of oil, and another candidate well completed with an open hole technique had a production rate of 236 tons of oil. These two wells were the most prolific in the Zhaodong oilfield. Using relatively basic engineering work integrated with simple economic calculations, this methodology is far less complicated and costly than computer simulation modeling for the operator. The performance in the Zhaodong oilfield reinforces this methodology used for selecting the proper candidate and completion process, providing more value and confidence for offshore operators.

In 2010, the sewage sludge production rate will be 178,500 t dried solids (ds) for Beijing and 294,000 t-ds for Shanghai, respectively. Beijing adopts a centralized system to stabilize 78% of her sludge in three rural Stabilization Centres. Aerated composting technique will be used. Shanghai on the contrary decentralizes the management plan to treat the sludge on site. Diverse treatment trains, such as aerobic/anaerobic digestion, drying, incineration, and composting will be applied. Production rate, treatment plan, and the associated costs, energy consumption, carbon dioxide emission, and risk assessment for heavy metals and pathogens on human health were evaluated in this report for sludges yielded in Beijing and Shanghai, China.

Efficiency And Productivity

This paper reports a case study using a standardization process for increasing efficiency and a better optimization of resources in a printing company with 150 operators having manual and mechanical tasks in the box assembly department along with four production lines. The current capacity is 350 boxes per day, while the demand is 650 units, where the company is expected to pay large sums for overtime. Using work standardization, studying worker movements, timing, and workstations redesign, the main goal was to increase the efficiency and productivity indexes. After applying those tools, the inefficient movements in operators decreased from 230 to 78, eliminating 66% of the unnecessary movements, as well as the standard time in a workstation decreased from 244 to 199 s (18.44%) per each assembled box, and the production rate increased by 63.2%, that is, 229 units per assembly line a day, where overtime was reduced to zero.
