This study aims to scrutiny the performance of the petrochemical sector and the technological innovation life cycle. Also, the stage of the innovation life cycle for the sector is specified. Then, scenarios are designed to improve the speed of the sector development. For this reason, for synchronizing the petrochemical sector, this study tries to combine two innovation systems (technological and sectoral systems) called “techno-sectoral innovation system” under an integrated model. Furthermore, the “functions and driving motors” are expanded in the proposed model.

By combining two concepts of the innovation systems, the complexity of the system rises to some extent. Also, to model causal relationships in the sector and non-linear connections between variables, system dynamics approach is applied. During this phase, the flow diagram of the model is translated to a simulation programme using Vensim software. Model validation is investigated using a comparison of the actual with simulated values.

The results predict the functions state of the innovation system and detect activation of innovation motors in each stage of the innovation life cycle. Validation shows the acceptable error of the indices. It can be concluded that the sector is relatively in the development state. Four scenarios have been proposed for representing policies that sector uses to motivate its companies. The best scenario is the fourth one that divides resources with different weightings among companies to accelerate switching time between sector’s motors. Finally, the fourth scenario can improve the performance of the petrochemical.

The hybrid approach shows researchers that performance of an industry can be improved based on sectoral and technological at the same time. Thus, this case-based model can contribute to other researchers, as a base model. Also, it could be customized with parameters and the relationship between players and functions. Furthermore, a dynamic switch among the motors has been presented in the model.

The purpose of this paper is to model the relationship between “innovation systems” players and markets to indicate the “innovation functions” behavior during the petrochemical technology life cycle.

In a general classification, innovation systems are divided into four categories: technical, sectoral, regional and national. If two approaches are hybrid, their benefits would be combined. According to the sectoral structure of the governance model in Iran, in many sectors, such as petrochemical technology, the combination of one another with a sectoral approach is essential. Hence, this paper has introduced a new hybrid approach, called a techno-sectoral innovation system, and has used system dynamics as a methodology and a petrochemical industry as a case study.

The results predict the functions state of the innovation system and detect activation of innovation motors in each stage of innovation life cycle. Validation is investigated using Monte Carlo simulation that shows the error of the indices is acceptable. It can be concluded that the model is relatively in a development state and the motor of entrepreneurship functions.

This case-based model can help other researchers, as a generic model. It could be customized with the input parameters and relational flows of new cases, and functions (F1-F7) can show the result of each scenario made by the innovation analyst and the policymaker.

This paper aims to determine how a strategic innovation framework that integrates the concepts of innovation function, dynamic performance management (DPM) and system-dynamics (SD) modelling can measure performance in a supply chain (SC).

The paper provides a strategic innovation framework for an SC by considering three steps. First, a systemic intervention is presented based on the innovation functions that influence SC performance. Second, an analysis of the system's performance is proposed. Third, a model SD-based simulation is designed. The developed framework is explained by employing a case study of the Colombian pig sector SC.

The results reveal that identifying and synchronising the system's performance drivers associated with the innovation functions could improve the inventory in the SC.

On the one hand, managers can use the proposed framework to evaluate the innovation investments and understand their impact on operation performance (e.g. on inventories). On the other hand, policymakers may support decision-making to improve policy design (e.g. through investment in R&D).

Few studies discuss the impacts of innovation functions on SC performance. This paper aims to fill this theoretical gap and to contribute to the literature by suggesting a novel framework which includes innovation functions.

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.

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.

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.

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.
