What are the positive impact of Quantum Computing in terms of Energy Efficiency for Manufacturing Industry?5 answersQuantum computing offers significant potential for enhancing energy efficiency in the manufacturing industry. By leveraging quantum technology, businesses can optimize processes, simulate scenarios, and improve machine learning applications, leading to more energy-efficient operations. Additionally, the green quantum advantage threshold plays a crucial role in comparing the energy efficiency of quantum and classical computing hardware. This threshold depends on factors like the quality of experimental quantum gates and the entanglement generated in quantum processing units. Quantum computing can enable better decision-making for energy-saving strategies, such as in hybrid quantum-classical algorithms, ultimately contributing to reduced energy consumption and improved sustainability in manufacturing. Integrating quantum computing into manufacturing processes can lead to substantial energy savings and operational enhancements.
What are the energy cost in plant factory?4 answersPlant factories have varying energy costs depending on factors such as location, design, and operational choices. Energy consumption ranges from 6.2 to 12.0 kWh per kg of lettuce produced in the United States. In terms of purchased energy, greenhouses that utilize freely available solar energy for photosynthesis have an advantage over plant factories, which rely on artificial lighting. For example, the production of 1 kg of lettuce in a plant factory requires an input of 247 kWh of electricity, compared to 70-211 kWh in greenhouses in different locations. However, plant factories can achieve higher productivity and resource efficiency compared to greenhouses. They outperform even the most efficient greenhouse in terms of energy efficiency, with plant factories using 1411 MJ per kg of dry weight compared to 1699 MJ in the most efficient greenhouse. Additionally, plant factories can achieve considerable reductions in resource consumption, such as 100% reduction in pesticide use and 95% reduction in irrigation water use.
What are the available energy benchmarking applications or software?4 answersThere are several energy benchmarking applications or software available. These include residential building simulation software, regulatory application software, heating, ventilation and air conditioning related software, life cycle/cost analysis software. Another benchmarking computing application is configured to create a benchmark run for a segment of customer profiles, providing energy consumption values for individual customer profiles as well as an average energy consumption value for the entire segment. Additionally, there is an opensource multi-core benchmark called epEBench, specifically designed for evaluating energy efficiency in computer systems. Industry standard organizations such as TPC, SPEC, and SPC have also developed tests and benchmarks to measure energy consumption of computer systems, although their methodologies differ slightly. Finally, the Energy Slices approach is proposed as an energy benchmarking approach for existing buildings, which involves time slicing and selecting regression models based on actual data.
Relationship between energy and cost in manufacturing?4 answersThe relationship between energy and cost in manufacturing is a topic of interest in several studies. One study found that energy costs have a significant impact on unit product costs in certain manufacturing sectors. Another study examined the incidence of changes in energy input costs for U.S. manufacturers and found that a significant portion of these cost changes are passed on to consumers in the short- to medium-run. Additionally, rising electricity prices for industrial companies can result in lower international competitiveness, but savings in energy costs can be achieved through specific organizational methods. Furthermore, a study on discrete part production in manufacturing found that cost is dominated by labor rate and processing time, while energy consumption can be reduced through machine tool selection and scheduling. These studies highlight the importance of managing energy costs in manufacturing and the potential for cost savings through energy-efficient practices.
How equip e-commerce companies with a benchmarking tool?4 answersE-commerce companies can equip themselves with a benchmarking tool by developing a modular tool that allows for comparative benchmarking of different technologies with minimal re-implementation. This tool should implement the benchmark specification in a modular fashion, allowing different application servers to be inserted and experimented upon. Additionally, the tool should consider the diverse needs of small to medium enterprises (SMEs) and big businesses, and create a benchmark suite for e-commerce that takes into account different e-commerce business models. The business model plays a primary role in the development of an e-commerce benchmark, as it determines processes, transactions, and database and navigational designs. By following a roadmap and using purposefully created data, alternatives, and tools, e-commerce companies can successfully perform a benchmarking initiative to optimize their business processes and enhance the value of their products and services.
Double flexible job shop scheduling problem5 answersThe double flexible job shop scheduling problem involves scheduling machines and automated guided vehicles (AGVs) to optimize shop floor flexibility and productivity. This problem is NP hard and requires solving two problems simultaneously. A hybrid algorithm is proposed to solve the multi-AGV flexible job shop scheduling problem (MA-FJSP) by minimizing the makespan, total AGV running time, and total machine load. Another approach combines simulated annealing and genetic algorithms to minimize the maximum completion time in flexible job shop scheduling. A generalized flexible job shop scheduling problem is introduced, considering additional constraints such as machine capacity, time lags, holding times, and sequence-dependent setup times. Mixed integer linear programming (MILP), constraint programming (CP), and a Greedy Randomized Adaptive Search Procedure (GRASP) are used to solve this problem. The flexible flow shop scheduling problem with no-wait constraint is also addressed in the literature, focusing on flow optimization in manufacturing and processing industries.
