WELCOME

Within this website I'd like to introduce myself.






AUG. PRIEN - Hamburg

  • Last Planner & Takt Planning
  • Process & Change Management
  • Trainings and Workshops
  • On-site Implementation
  • BIM Management
  • BIM Automation

AUG. PRIEN gave me a headstart in terms of lean philosophy. I learned to think holistically, process and customer-oriented. That enabled me to pursue difficult change processes as part of the on-site implementation of lean methods.

Case Study: Facility Locations Planning

  • Logistics
  • XCargo Excel Add-In
  • Network optimization

Within the framework of this project, a logistics network was examined with the help of real data sets. For this purpose, the actual situation and the associated cost structure were visualised, analysed and subsequently optimised with the help of the XCargo program.

Aalto University
Erasmus+ Exchange

  • Entrepreneurship
  • Leadership and Change Management
  • Presenting skills

During my semester abroad I had the opportunity to learn finnish and to get acquainted with the finnish culture. During my studies I could learn more about entre-preneurship, creativity, design thinking, and leadership and combine that with the improvement of my presenting skills.

Goldbeck Südwest GmbH - Frankfurt

  • Protocols & Presentations
  • Quantity determination, Calculation & Offers
  • Lean Construction Management
  • Technical Procurement

GOLDBECK always accompanied me during my studies and gave me a lot of practical added value to the theory of my studies. During this time I was able to take a lot with me, both professionally and personally, in preparation for my future professional life.

Case Studies

  • Le Petit Chef
  • Big Splash Water Park
  • Retail Business
  • Activity Based Costing
  • Target Costing und Life Cycle Costing
  • Wind Farm

Within the framework of case studies the current portfolio of a company is examined and optimized. The aim is to develop a profitable solution with the help of key figures and various tools while taking into account the company's competitive strategies and goals.

Tutorship - Darmstadt

  • Preparation & Postprocessing
  • Supervision & Presentation
  • Tutoring

I really enjoyed my tutoring work in accounting and cost and performance accounting. Especially the interaction with the students as well as the imparting of knowledge was in focus for me.

Interdisciplinary Project "Construction and Environment"

  • New planning of a railway bridge on route 3550

Within the framework of this project, a dilapidated existing bridge was to be replaced by a new bridge. The new design should take into account structural, traffic and construction aspects. Thematically, project management and the use of digital tools such as BIM and object monitoring played also an important role.

Masterthesis

An investigation into the notification of supply logistics processes in the construction industry

Efficient construction logistics processes are one of the success factors in the realisation of construction projects especially in urban areas where these processes become particularly complex. In the context of my masterthesis, the supply logistics of an inner-city construction site is to be documented, evaluated and to be scientifically investigated. Especially the reliability of a delivery management system is investigated.

Delivery Management System

Delivery management systems are systems to register transports. The basic principle is that transports are registered in advance via a web-based system which assigns the corresponding transport a time window. The focus of this thesis is on the foundation, relevance and reliability of these systems.

The Problem

Imagine that there are a number of orders to be executed within a high-bay warehouse, each of which has a due date.

The Question

In which order should the jobs be executed so that the total delay is minimized?

The Solution

The problem is solved using the metaheuristic of the Tabu Search which was tailored to the problem. Furthermore, these adaptations were tested and evaluated with the help of the following therefore specially designed programs.

The Benchmark-Generator

With the help of the Benchmark-Generator any instance of the high-bay warehouse problem can be created. The generated instances can then be used for standard solvers (e.g. IBM ILOG CPLEX Optimization Studio) or for the following execution program of the Tabu Search.

The Tabu Search

The Tabu Search program can be used to open the previously created instances and the "Tabu Search ausführen" button can be used to optimize them by using the heuristic. Finally, the program returns the best solution found. There are also numerous test and evaluation functionalities. For example, orders can be entered manually or individual components of Tabu Search can be tested. For further examination of the data or for the creation of plots a comprehensive evaluation protocol can be generated.
