Production is the most fundamental activity in our economy. In this paper, a Cobb-Douglas production function is used as the mathematical model to describe the relationship among production, labor and capital. Two reliable production optimal control problems are studied. Algorithms to find dynamic optimal control intervals are provided with interval parameter presentations and interval computat...

This study reports the results of farmers’ production via irrigation resources utilization and efficiency parameters technical allocative by way sustainable environmental economics. The hypothesis is that factors affect in scheme as Data from cross section panel data were used then productivity measurement function are outlined two scenarios: first, report such output elasticity determine ineff...

The Douglas–Rachford algorithm is a popular method for finding zeros of sums of monotone operators. By its definition, the Douglas–Rachford operator is not symmetric with respect to the order of the two operators. In this paper we provide a systematic study of the two possible Douglas–Rachford operators. We show that the reflectors of the underlying operators act as bijections between the fixed...

Genetic algorithms GAs are multi dimensional and stochastic search methods involving complex interactions among their parameters For last two decades re searchers have been trying to understand the mechanics of GA parameter interac tions by using various techniques careful functional decomposition of parameter interactions empirical studies and Markov chain analysis Although the complex ities i...

The effectiveness of direct volume rendered images depends on finding transfer functions which emphasize structures in the underlying data. In order to support this process, we present a spreadsheet-like constructive visual component-based interface, which also allows novice users to efficiently find meaningful transfer functions. The interface uses a programming-by-example style approach and e...

In this paper we consider the specification and estimation of the Cobb-Douglas production function model. After reviewing the "traditional" specifying assumptions for the model which are based on deterministic profit maximization, we develop a model in which profits are stochastic and in which maximization of the mathematical expectation of profits is posited. "Sampling theory" and Bayesian est...

In this note we show that in a pure exchange economy with two agents and a finite number of goods, there exists no strategy-proof, Pareto efficient and nondictatorial social choice allocation function on any local Cobb-Douglas preference domain. This is a slight extension of a result proved by Hashimoto (2008).

This paper studies the effects of heteroscedasticity on the following five types of estimators: (1) Data Envelopment Analysis (DEA) per se as well as DEA joined to regression forms, (2) Corrected Ordinary Least Squares based on maximum residual (COLS-R), (3) Corrected Ordinary Least Squares based on moments of residuals (COLS-M), (4) Maximum Likelihood Estimation (MLE), and (5) Goal Programming...
