utility consumption
1.Improve co-packer performance so as to meet the targets of material yields, utility consumption, quality index, labor costs and order fulfillments.
3.By the comparison theorem, a series of properties of the backward-forward differential utility process is gotten, such as time consistence, monotonicity with respect to the terminal value, monotonicity with respect to the consumption and concavity.
4.Under the market conditions supposed in Black-Scholes model and assumption that an investment object is a European call option,in this paper an investment-consumption problem is investigated. A utility maximization model is constructed.
5.Applying marginal utility theory, investment multiplier principle in economics and tax fairness and efficiency theory in tax, supported by a large amount of authoritative data, combining qualitative analysis with quantitative analysis, this paper explored to study the feasibility, necessity, reality significance of the transition of VAT from production type to consumption type from type analysis, international reference, implementing situation, finance influence, international competition and investment, etc.
6.The dynamic programming technique initiated by Bellman and ITO stochastic analysis technique are very important,which are applied by Merton and Breeden to study how the individual make decisions of investment or consumption to maximize lifelong utility in uncerten circumstances drived by stochastic processes.
