Core Design Rules

🍏 core design rules for each configuration in optioneer, there are a set of "core" design rules that must be enabled in all cases global parameters technical design rules penalty design rules cost design rules asset installation priority the flow of data begins with global parameters for electricity assets or with the technical design rules for pipelines and offshore assets we then define the technical, cost and penalty inputs for each asset and the outputs are sent to the asset installation priority component this component determines where to put each asset let's dig into this a bit more 🌏 global parameters groups together parameters that are used across a project this is done to maintain the consistency of values across the project this includes parameters such as the cost of concrete or the cost of earthworks this design rule must be activated, if available affects the generation of routes and affects the outputs of optioneer 🔨 technical design rules defines the technical limits and physical chracteristics for assets these vary for each asset but it allows you to define no go zones (based on the gis layers) maximum elevation an asset can be installed at maximum slope an asset can be installed on along with other technical limits other asset specific parameters (such as overhead line spans, underground cable depths and pipeline material characteristics) not captured within docid\ tfvxo7liwgk0waxc0apkv technical design rules must be activated for all assets you would like considered affects the generation of routes affects the outputs of optioneer ⚠️ penalty design rules penalties are the mechanism by which optioneer understands if things are good or bad to traverse whilst routing traditionally, constraints are handled qualitatively e g "avoid at all costs" or "minimize impact where possibe" optioneer quantifies these classifications to reflect any combination of the following risk, impact, cost, or policies the table below demonstrates how we convert a more traditional qualitative based routing approach to constraints to a quantitative based system an exponential scale is utilised for penalties for more representative modelling of constraints penalty feeds in the multi objective optimisation (moo) functionality of optioneer, in that penalties are one of the objectives that optioneer aims to minimise in other words, optioneer aims to minimise the distance traversed through constraints such as woodland and steep slopes and so, this design rule must be activated for all assets that you want to be considered penalty design rules must be activated for all assets you would like considered affect the generation of routes affect the outputs of optioneer make up one of the objectives optioneer aims to minimise 💰 cost design rules cost is a fundamental metric for any infrastructure development optioneer contains a capex model which takes account of 🪨 materials such as steel towers, or pipe materials 🙅 crossings including specialised installation methods 🛣 incurred costs from traversing constraints or following of infrastructure cost design rules will vary depending on the assets you are considering similar to penalty design rules, the costs feed into the moo functionality of optioneer and so is one of the objectives that optioneer aims to minimise cost design rules must be activated for all assets you would like considered affect the generation of routes affect the outputs of optioneer make up one of the objectives optioneer aims to minimise 🥇 installation priority this design rule implements the multi asset functionality in optioneer it selects an asset type at each point along the route based on technical limits and a user defined priority each asset must be ranked in order of preference (1 = lowest, 4 = highest) this priority will often reflect the cost or preference of the asset type for that development the asset installation priority design rule will first determine the candidate assets along the length of the route this is all of the assets that can be placed at every point along a route based on the technical limits it will then reference these candidate assets against the user defined priorities to yield the selected assets for each route where more than one asset can be placed on the route, the asset with the highest priority will be selected subject to no technical limits being exceeded this design rule must be activated affects the generation of routes and, affects the outputs of optioneer
