“…The energy demands were also obtained for houses 3-8 in Figure 2. According to equation (2) in the newsboy model, the optimal energy supply d opt was calculated to be 0.4 kW/house. Since our basic model consists of eight houses (K=8), the power plant should generate 3.2 kW per hour for our model smart city.…”

An urgent need for energy management has emerged all over the world because ever growing consumption demands will eventually surpass the supply of critical resources. Energy management should be more effective and efficient in smart cities. In this study, we propose a method for the energy management with a battery system of a smart city. An energy supply is optimized using the newsboy model. Energy management is discussed in light of optimization and the need to cater to demands for excess energy. A basic model of a smart city with a battery system is constructed. The model consists of eight houses and a power station. A battery is implemented in each house to supplement an energy shortage. The objective is to find the optimal energy supply which minimizes the cost function. The optimal energy supply and the minimum cost are varied with the cost coefficients for surplus and shortage of energy. First, the optimal energy supply is estimated if the cost coefficients are the same for surplus and shortage of energy. It is 0.4 kW/house; however, different battery systems are required for eight houses with different energy demands. Second, the effects of cost coefficients are investigated. The battery system is more required with a higher cost coefficient of energy surplus. The power station should supply a larger energy to a smart city with a higher cost coefficient of energy shortage. Actual energy demands on different types of buildings should be examined in greater detail for more effective and efficient energy management for a smart city.

Since Industrial Revolution and the division of labor, the wealth of nations is more and more increasing. Although the smaller division of labor is better in GDP, but mass production with larger lot (quantity) is better since Fordism and the division of quantity (lot-size , 0 Q Q < < ∞ ) is well-known to be worse in manufacturing, for the sake of the larger set-up with penalty. This paper presents the progressive discipline for the contradiction on modern economic growth in the lot-sizing scheme. The theory would govern over from mass-production (larger Q), mid-lot (EOQ) and disparities (smaller Q), toward next to sharing equilibrium ( 0 1 Q < < ). Especially, the Nash's condition for the case of 1 Q < could be obtained by the duality of flow line vs. job shop. This theoretical review would give the further wealthy development to the gap-wider society of artifacts in the future, and point out that the shared society too could be balanced on the base of the harmonic mean under Industrial-financial capitalism.
