The results show that the flexible design that expands capacity based on the decision rule generated by our proposed framework outperforms the design with a fixed capacity expansion plan.
Worldwide renewable energy capacity rises 10% in 2022, but much more is needed. Global renewable energy capacity increased by 9.6% last year, the International Renewable Energy Agency (IRENA) says. Wind and solar power accounted for 90% of the net additions, and almost half of the new capacity was added in Asia.
Strategic capacity planning for multiple-facility systems with flexible designs is an important topic in the area of capacity expansion problems with random demands. The difficulties of this problem lie in the multidimensional nature of its random variables and action space.

Current water capacity expansion scheduling approaches used by water companies in England are based on deterministic annual supply-demand balance (Padula et al., 2013). However, present investment decisions need to account for significant uncertainty. The proposed flexible and adaptive approach is applied to London''s water supply
Usually, the decision rule for flexible capacity expansion is formalized as follows: IF v (ξ t k) ∈ C THEN exercise the flexibility (i. e., expand the capacity) ELSE do nothing where v (ξ t k) is a. Case study. This section demonstrates how the proposed framework can be used to generate decision rules, with the goal of flexibly deploying an
By the end of October, China''s total installed power generation capacity reached about 2.5 billion kilowatts, rising 8.3 percent year on year, data from the National Energy Administration showed.

Dynamic expansion of flexible capacity under demand uncertainty is studied. Pricing coordination and non-coordination is modelled in a two-level decision framework. The interplay between short-term pricing and long-term capacity decisions is analyzed. Adopting a coordinated pricing decision strategy can reduce capacity
Usually, the decision rule for flexible capacity expansion is formalized as follows: (4) IF v (ξ t k) ∈ C THEN exercise the flexibility (i. e., expand the capacity) ELSE do nothing where v (ξ t k) is a function of realized uncertainties and C is the criterion. Note that C is a vector representing multiple criteria for the realized
A flexible capacity expansion strategy is important for engineering systems since it enables decision-makers to adjust the capacity of systems as uncertainty unfolds. In a flexible capacity expansion problem, how to generate the optimal decision rule to determine when and how to expand the capacity is a challenging task. In this
Dynamic expansion of flexible capacity under demand uncertainty is studied. • Pricing coordination and non-coordination is modelled in a two-level decision framework. • The interplay between short-term pricing and long-term capacity decisions is analyzed. • Adopting a coordinated pricing decision strategy can reduce capacity
Exploring future pathways for reservoir storage capacity expansion and its storage capacity potential within an integrated multisectoral system can inform both short-term and long-term strategic planning. Additionally, understanding the feedbacks between evolving water infrastructures and the coevolution of the human-Earth systems can elucidate
Flexible energy storage capacity A lot of home batteries are somewhere in the 10 kWh to 15 kWh range, which is pretty standard as far as capacity goes. But a capacity upgrade on a non-modular
An interesting result of the study is that the proportion of flexible capacity acquired decreases with increasing scale economies. We also find that investment in flexible technology is significant even when it is relatively more expensive than dedicated technology. Erlenkotter, Donald,Pre-investment Planning for Capacity Expansion: A
Also, in another paper by Hu et al. [13], a simulation-based approach is introduced to create a decentralized, flexible waste management system in the face of uncertainties in demand for capacity
Exploring the coordinated capacity expansion planning with the interaction of flexible resources toward future power system development is yet to be investigated. The reliable and secure operation of the power system and RES generation accommodation and are closely associated with the configuration mixes of the power system and the portfolio
The expansion of our PFAS testing capabilities will enhance throughput, secure faster turnaround times, offer more comprehensive investigations and ensure better targeted remediation analysis. SGS announces that it is quadrupling its testing capacity of per- and polyfluoroalkyl substances (PFAS) across North America. This will enhance
SABIC SK Nexlene Company (SSNC), a joint venture between SABIC and SK Geo Centric, has announced plans to expand the capacity of its plant in the South Korean city of Ulsan to produce advanced material solutions. The expansion, which is due to come on stream in the second quarter of 2024, targets applications in solar panels, vehicles, footwear
But adding manufacturing capacity isn''t one size fits all. The direct effects of bandwidth and labor shortage issues vary among small, medium, and large companies. That''s why flexibility is key. Being able to fill the gaps with flexible solutions that keep pace with your growing capacity needs is essential. ElevateBio experienced this
You''ll need flex capacity whenever the demand for resources oustrips your current capabilities. Resources could mean employees, time, skills, or management capacity. The best fit for flexible resources is when you have a project that developers can ramp up on quickly. This usually means. Low domain expertise required.

Advantages of the Lag strategy. Minimizes costs: The lag strategy is the most cost-effective approach to capacity planning. You save on resource costs because you only add capacity when needed. As a result, it helps avoid unnecessary expenses. Reduces risk: The lag strategy can reduce the risk of excess capacity.
