Abstract Background Farm productivity on smallholder family-owned crop farms remains low despite several interventions to transform agriculture especially in developing countries. Farmers rural areas face serious constraints that impede their productive capacities for the principal dietary staple, notably maize. Smallholder farmers have access unprofitable markets turn make enterprises less pro...

in this article, non radial method of dynamic dea with the parallel network structure is presented and is used for calculation of relative efficiency measures when inputs and outputs do not change equally. in this model, dmu divisions under evaluation have been put together in parallel. but its dynamic structure is assumed in series. since in real applications there are undesirable inputs and o...

This paper establishes a link between investment in financial market infrastructure and its governance structure as either a user-oriented or a for-profit organization. The infrastructure is used to ensure that capital can be allocated through financial trades. It is shown that only a user-oriented infrastructure that allocates costs appropriately across different user groups can achieve effici...

For the continuous manufacturing processes, the integrated optimization for production planning, scheduling, and dynamic optimization usually leads to profit improvement and better overall performance. The challenge is that the integrated optimization is often a large scale problem which is difficult to solve. To deal with the computational difficulty of the integrated problem, we first propose...

This study mainly focuses on enhancing the overall efficiency of gas transmission networks. The authors developed a model with detailed characteristics of compressor and pressure reduction stations. Following this, they suggested three different systems with gas turbine including: organic rankine cycle (ORC), air bottoming cycle (ABC), and ABC along with steam injection (SI-ABC). In addition, u...

abstract comparative advantage is one of the important economic criterions in production, import and export programming. in this survey, existence and nonexistence of the most important vegetables(potato, cucumber and tomato) comparative advantage in jiroft aria in the year 1385-86 by use of two comparative advantage recognition indexes was determined. the first indexes were social cost benefit...

The paper examines the behavior of the Chinese state owned enterprises after the reform. The focus is on the key issue of government-enterprise interaction. Based on theoretical analyses and empirical tests, I argue that despite facing strong profit incentives, many of the Chinese state-owned enterprises are still greatly influenced by the government and dependent on the government. They behave...

As compared to the traditional advertising, the word-of-mouth (WOM) communications have striking advantages such as significantly lower cost and rapid delivery; this is especially the case with the popularity of online social networks. This paper addresses the issue of maximizing the overall profit of a WOM marketing campaign. A marketing process with both positive and negative WOM is modeled a...

Aspects referring to the formation of portfolio of projects for investments in informatization programs are approached: criteria of efficiency, general problem, aggregate problem in continuous form, general problem in discrete form and solving of problems. As criterion of informatization projects’ economic efficiency, the total profit maximization due to investments is used. In preliminary calc...
