I need a clear, two-part analytical workflow that I can run and update myself. Part I – London Underground resilience Using network science methods, quantify how individual and multiple station closures alter overall connectivity, with passenger flows taking priority in the metrics you develop. I am especially interested in before-and-after comparisons that highlight critical stations and show where flows are most vulnerable. Part II – Retail location modelling Build a spatial interaction model that draws on census-based population counts, current supermarket locations and inter-zonal distances. Run two alternative location scenarios for a proposed new store and report predicted demand share for each. An accessibility check must round off the analysis, focusing on a 15-minute walking catchment and related walking-distance indicators. Deliverables • Clean, well-commented code (Python) and any GIS project files (jupiter notebook) • A concise technical report that explains data sources, methods, key assumptions and findings, with figures that can drop straight into a slide deck • Step-by-step instructions so I can reproduce results on my own machine Please keep external dependencies to widely used, open-source libraries where possible and document anything that needs special setup.

Hi, I’m a Senior Data Science Engineer with 20+ years in Python and quantitative modelling. I have gone through your specific requirement for network and spatial modelling I built something like this for quantitative clients using Python for data driven workflows. I would use NetworkX over a custom graph implementation because closure analysis needs reliable path and connectivity calculations before adding passenger flow weights. I will build a Python Jupyter notebook covering station closure scenarios, passenger weighted connectivity and critical station analysis. For retail, I will build the spatial interaction model with census data and GIS distance measures, then compare both store scenarios. And I will add the 15 minute walking catchment analysis with reproducible figures, at least that is where I would start. Relevant Python and data modelling samples I can send. Which London Underground passenger flow dataset do you already have? Which two proposed store locations should the scenarios use? Do you already have census zones and walking network data, or should those be sourced? Free for a quick call this week? Or answer those three and I’ll map the notebook structure. Dev Singh

I got you! I can build your two-part analytical workflow in Python/Jupyter, covering London Underground resilience with flow-prioritised network metrics and retail spatial interaction modelling with demand-share scenarios and 15-minute walking accessibility outputs. I’m ready to handle the data preparation, modelling, clean commented code, GIS-ready outputs, report figures, and reproducible setup instructions. I’m young, a fast learner, available 24/7, and focused on making the workflow easy for you to rerun and update. Get the demo first before you pay. A couple of key questions: Do you already have passenger flow data for the Underground, or should I use publicly available TfL/estimated OD datasets? For the retail model, do you have specific candidate store locations and supermarket competitor data, or should I source these from open datasets like OSM/census sources? Let’s chat and discuss the answers so I can start with the right structure. Kind regards, Haroon Z

Hello!, I am a Florida-based senior software engineer and this project stands out because it needs more than analysis, it needs a workflow you can actually run, update, and rely on. What I think you need is a clear, two-part system that turns a complex resilience and retail modeling problem into something structured and repeatable. I can handle it in practical phases: define the input data and assumptions, build the Python analysis pipeline, add statistical modeling and simulation, then deliver clean visual outputs and documentation so you can maintain it yourself. I’m careful with the details that usually get missed in work like this, especially where urban planning logic, data quality, and explainability all matter. My goal is to keep it simple enough for you to use, but strong enough to scale as new data comes in. Relevant work examples: - infrastructure risk forecasting tool for a regional planning team - retail demand simulation dashboard for a multi-location operator - Python scenario model for transport disruption analysis - data visualization workflow for a policy research group A few quick questions: 1) What inputs do you already have for Part I, and in what format? 2) Do you want the final deliverable as a notebook, script package, or dashboard? 3) Is your main priority explainability, or stronger predictive accuracy? If helpful, I can sketch the full workflow first so you can see exactly how I’d approach it. -James

Hi, I went through the zip and your checklist doc, so I've got the Havering set, sites A and B with the two store sizes, and the graph for the tube part None of it is new ground for me. Nearest thing I've done is a snowfall forecast model for a meteorologist, calibrated on ten winters, walk forward validated, and handed over as a package he runs himself, with a README written for someone installing Python for the first time. Same shape as this, a model that holds up plus something you can rerun without me Stack would stay boring on purpose, networkx, osmnx, geopandas, pandas, so setup is a pip install and nothing strange to configure I'd keep the notebook in your section order so every output maps to a numbered part, figures saved as separate pngs so they go straight in the deck, and the write up built around the tables instead of repeating them

Hi, I hope you are doing well. Very happy to bid your project because my skills are fitted in your project. I have strong experience with Python, network science, spatial/GIS analysis, transport networks, accessibility modelling, and data-driven location analysis using NetworkX, GeoPandas, Pandas, OSMnx, and Jupyter. I have worked with graph connectivity, passenger-flow metrics, spatial interaction models, census data, distance matrices, catchment analysis, and reproducible analytical workflows. I will build the London Underground network model and quantify the effects of single and multiple station closures using connectivity, flow-weighted resilience, criticality, and before/after vulnerability metrics. I will develop the retail spatial interaction model using population, supermarket locations, and inter-zonal distances, compare two proposed-store scenarios, and calculate predicted demand shares together with 15-minute walking accessibility indicators. I will deliver a clean Jupyter/Python workflow, GIS-ready outputs, presentation-quality figures, a concise technical report, and step-by-step instructions so you can update the datasets and reproduce the complete analysis independently. If you send the message, we can discuss the project more. Thanks.

Hi there, I can build this as a reproducible Python workflow covering both the London Underground resilience and retail modelling. For the Underground analysis, I’ll use passenger flows as a key weighting factor, compare network connectivity before and after individual and multiple station closures, identify critical stations, and visualize vulnerable flows clearly. For the retail component, I’ll build the spatial interaction model from population, supermarket locations and inter-zonal distances, run both proposed store scenarios, calculate demand share, and complete the 15-minute walking accessibility analysis. I’ll deliver a clean Jupyter notebook, commented Python/GIS files where required, presentation-ready figures, a concise technical report, documented assumptions and step-by-step reproduction instructions. I’ll also keep dependencies limited to established open-source libraries and document any setup required. Looking forward to working with you. Thanks
