Abstract

Purpose

Urmia lake water has impressively decreased recently and seriously endangered the lives of the inhabitants. In this paper, the effects of various factors on the reduction of the lake water are investigated and appropriate scenarios are proposed for future improvement. Due to the significant impact of agricultural issues on this crisis, this paper has focused specifically on agriculture. So, this paper aims to forecast and improve the lake water level.

Design/methodology/approach

In this paper, a system dynamics (SD) model, which is capable to consider various parameters and variables affecting the lake water level within nonlinear and dynamic relations, is developed.

Findings

To show the effectiveness of SD model, real data are used to run the model and the results show that the actual behavior of the lake water is reproduced with high validation (around 98.28 per cent). Also, five different scenarios are proposed to increase lake water volume. The hybrid Scenario 5 (which combines three other scenarios including increasing irrigation efficiency in the agricultural sector, changing cultivation pattern of agricultural products and returning some dams’ water that are consumed in the agricultural sector into the lake) is chosen as the most effective scenario for increasing lake volume about 15 billion m3.

Originality/value

The main contributions of this paper are systemic view to the whole problem, paying attention to the agriculture subject as one of the most important issues, considering many critical variables (e.g. evaporation, salinity and precipitation) and providing improvement policies along with assessing the effects of them.

Abstract

The current information system use in quality management and ISO 9000 certification process is typically utilized in administration and documentation. The existing software do not satisfy the technical information needs for ISO 9000. There is a need for tools that can help management to decide on technical aspects such as proper corrective and preventive actions or design verification and validation activities. This paper analyzes the information requirements of ISO 9000 standards and identifies the areas where a decision support system can be used. Further, it proposes a conceptual framework for company‐wide information management, while it explains the modular approach to the system development by introducing and empirically testing the prototype model for a corrective and preventive actions module. The proposed system will provide the conceptual structure for a quality assurance information system within organizations.
