In today’s dynamic business environment, a key challenge for all companies is to make adaptive adjustments to their manufacturing strategy. This study demonstrates the competitive priorities of manufacturing strategy in hydro-power case company to evaluate the level of sustainable competitive advantage and also to further analyze how business strategies are aligned with manufacturing strategies. This research is based on new holistic analytical evaluation of manufacturing strategy index, sense and respond, and sustainable competitive advantage models. These models help to describe, evaluate, and optimize resource allocation to meet the performance requirements in dynamic decision making. Furthermore, these models evaluate operational competitiveness for manufacturing strategies according to the multi-criteria priority. The results show that the adjustments of competitive priorities in manufacturing strategies by implementing the proposed holistic analytical models are helpful in strategically managing business operations. The discussion derives the most critical attributes in business operations while alignment of resource allocation with competitive priorities help to strategically focus those attributes. In conclusion, we argue that resource allocation and manufacturing strategies have become the most important capabilities in a business environment where companies focus to get a sustainable competitive advantage.

“…Further model transformation is required due to the stage reduction in Section 3.1.2. Notice that j (�1, 2, 3, 4) in the intermediate model (12) refers to the first four operational stages. Here, we use symbol t to replace the corresponding j and then integrate stage t � 2, 3, 4 into the first stage (t � 1) as illustrated in Section 3.1.2. e way how to transform is similar to that in Section 3.2.1.…”

“…Because the random inflows fluctuate with seasons, we assume the water inflows of each candidate take the same uncertain level in each season. us, for the MSSP model, 16(�2 4 ), 256(�2 8 ), and 4096(�2 12 ) stagewise scenarios are constructed, respectively. Furthermore, according to the generation and simplification process of the scenario set displayed in Section 3.1, 16 scenarios are generated for the two-stage DE model.…”

“…Besides the above assessment models, the optimization technique becomes another alternative in recent years. For example, Hosnar and Kovač-Kralj [12] identify the optimal installation locations by maximizing an ecoprofit objective at technological, economic, environmental, and social constraints. To identify the appropriate hydropower dam location, Loannidou and O'Hanley [13] develop a mixedinteger linear programming model to optimize the hydropower potential with the consideration of river connectivity.…”

In the location-related planning of a hydropower system, the consideration of future operations under uncertainties can make the decisions sustainable and robust. Then, it is of great importance to develop an effective approach that deals with the long-term stochasticity due to the long-lasting effects of the location selections. Thus, we propose a multistage stochastic programming model to optimize the planning decisions of cascade hydropower stations and the long-term stochastic operations in an integrated way. The first stage (i.e., the planning stage) in the model deals with the location and capacity decisions of the hydropower stations, while the subsequent stages implement the scheduling decisions under each stagewise stochastic scenario. To address the curse of dimensionality caused by the long-term stochastic operations, we further propose a novel dimensionality reduction approach based on dual equilibrium to transform the multistage model into a tractable two-stage stochastic program. The applicability of our approach is validated by a case study based on a basin of Yangtze River, China, and corresponding sensitivity analysis.

“…[11] presented a probabilistic approach for the generation reliability evaluation of municipal waste water based micro-hydro power plant. The optimal installation location of water capture within a hydropower plant was obtained in [12] using mixed-integer nonlinear programming method. Thirteen hydro-turbine system architectures were used to select the most appropriate turbine architecture for a low-head small scale hydro specification in [13].…”

One of the biggest challenges facing the world today is to provide access to sustainable, safe and affordable electricity supply. Small-hydro or micro-hydropower is considered as one of the most cost-effective, reliable and clean sources of renewable energy. Egypt has a long river which is a very good energy source. Many small and micro-hydropower plants can be installed in run-of-river schemes or implemented in existing river infrastructure. Egypt has to make use of its hydro
