- PostA Dive Into Manually Picked Seafood Distributing Warehouse Optimization An investigation of how to create more efficient manual picking processes in seafood distributing warehouses(2023) Widlöf, Matilda; Oresten, Tryggve; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Lantz, Björn; Lantz, BjörnSeafood distributing warehouses struggle with low efficiency. It is an industry where historically low focus has been placed on developing the warehouses capabilities meaning that they have typically lagged behind other industries. There exists plentiful literature on the best practice of designing ware- houses but none which tries to adapt the best practice to the particular circumstances of the seafood distributing industry, a gap this study aims to bridge. Through an abductive case study focusing on theory elaboration the specific context was understood. Literature was used to find the best tools to use for the setting and in the case of storage assignment strategy simulations were utilized in order to evaluate the best technique. The results of this thesis indicate best ways of designing warehouses when it comes to their shape, layout, batching method, zoning methodology, choice of pallet racks and storage location assignment method for article placement. Of special interest is the best storage location assignment method found by the study which solely utilized frequency of demand for allocating storage spaces, though there exist methods this study did not attempt which might be superior. The study investigated cluster based models incorporating association into the model but these were shown to be subpar. Practical consequences of implementing the guidelines presented by this study include a more resource efficient manually picked seafood distributing warehouse with shorter lead times and more efficient storage.
- PostInvestigation of Portfolio Strategies(2016) Bore, Alexander; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and EconomicsThis thesis creates a model for simulating stocks and interest rates to compare portfolio strategies. The two portfolio strategies used in the thesis are CPPI and OBPI. CPPI (constant proportion portfolio insurance) is a dynamic strategy that changes the amount in the risky asset and the safe asset at every timestep. OBPI (option based portfolio insurance) is a static strategy that invest an amount in the stock and the put option. It is found out that OBPI performs better in a decreasing market and that CPPI performs better in an increasing market. The model used in this thesis can be seen as an extended Black-Scholes model. The stock will be modelled as a NIG (normal inverse Gaussian) with GARCH as stochastic volatility. The interest rate is modelled by a CIR (Cox, Ingersoll and Ross) model. There are some problems with this model, but it is better than the Black-Scholes model. Keywords:
