Hi, I'm Tristan Wernli

Welcome to my portfolio. Here you’ll find a curated collection of case studies from warehouse automation, supply chain, industrial engineering and industrial perspectives. Scroll down or use the buttons below to navigate by topic.

Warehouse Automation

Warehouse Automation

Highspeed Workstation

A high-performance commissioning workstation can turn peak-driven dental fulfillment into a stable and predictable process. Goods-to-person workflows, ergonomic design and guided picking help increase throughput, reduce operator strain and maintain picking accuracy without adding staff. This case study explains the business challenge, workstation concept and operational impact in more detail.

Warehouse Automation

Robot Picking

Robotic picking can help turn extreme Monday peaks in e-commerce fulfillment into a more stable and predictable workload. By using autonomous weekend pre-picking and prepared buffers, a large share of the backlog can be processed before the regular week starts, without adding weekend staff. The article breaks down the process concept, commercial model and resulting operational improvements.

Warehouse Automation

Celluveyor
Technology

Software-defined conveyor technology can make critical material-flow nodes more stable and adaptable in grocery online fulfillment. Omnidirectional diverter and alignment modules help reduce micro-stops, improve carton positioning and keep dispatch flows reliable during peak periods. The article breaks down the material-flow challenge, cv.GO concept and resulting operational improvements.

Supply Chain

Machine Learning

E-Commerce Delivery Time Prediction

Machine learning models create value when data quality, feature design and evaluation fit together. This article shows how e-commerce order data was prepared, transformed into predictive features and used to compare a Linear Regression baseline with a HistGradientBoostingRegressor. It highlights why leakage control, residual analysis and feature importance matter beyond the final score.

Forecasting

Transport Volume Forecasting Analysis

Transport volume forecasting helps logistics teams estimate future delivery volumes and required hub capacity more accurately. This case study compares Excel Forecast Sheet, Holt-Winters and AI-based forecasting using four years of anonymized weekly data from a Swiss transport and logistics company. It shows why forecast accuracy, bias control, calendar effects and operational validation are critical for reliable capacity planning.

Sourcing Strategy

Make-or-Buy Analysis

Manufacturing cost optimization creates value when design, process and sourcing decisions are considered together. This case study shows how a high-volume floor support was analyzed to reduce cost through larger support spacing, riveting instead of welding, more efficient powder coating and lower transport volume. It highlights that successful make-or-buy decisions depend not only on unit cost, but also on lead time, design maturity, standardization and cross-functional planning discipline.

Industrial Engineering

Industrial Manufacturing

Adhesive Bonding Implementation

Adhesive bonding only creates value when mechanical validation, production economics and shopfloor execution are aligned. This case study shows how a wear-prone keyed shaft connection on a diverter roller was replaced by a bonded shaft-hub concept. It explains why the technically strongest solution is not always the best implementation path and why batch size, investment level and process reliability are critical when introducing a new manufacturing method.

Mechanical Engineering

Highspeed Workstation Development

SpeedCom reflects the full journey from early product concept to prototype testing, market launch and series production. The article summarizes the key development phases, including engineering, cross-functional collaboration, endurance testing and the LogiMAT trade show presentation. It shows how a high-performance picking workstation was brought from an initial idea into Stöcklin’s product portfolio.

Industrial Perspectives

Factory Systems

Inside UK Factories

Factory visits create value when production logic, automation level and supply chain context are understood together. This article reflects observations from MINI, Triumph, Morgan and Jaguar & Landrover and compares how different manufacturers approach scale, flexibility, ergonomics, bottlenecks, traceability and vertical integration. It shows why there is no single right production system and why industrialisation depends on product complexity, production volume and strategic positioning.

Economic Policy

Taxation & Innovation

Innovation is shaped not only by talent and ideas, but also by tax policy, research ecosystems and talent mobility. This article reflects insights from a University of Basel lecture by Prof. Stefanie Stantcheva and explains how personal taxes, corporate taxes and local innovation ecosystems influence where top inventors work and how much they innovate. It shows why tax policy can affect innovation, but why education, research infrastructure and strong regional ecosystems are just as important.
