2 Χωροθέτηση Επιχείρησης

3 Η σημασία της χωροθέτησης Η χωροθέτηση μιας επιχείρησης έχει μεσο- μακροπρόθεσμα καταλυτική επιρροή στο κόστος λειτουργίας, στην τιμολογιακή πολιτική και στην γενικότερη ανταγωνιστικότητα της επιχείρησης. Εξαγωγές: 1962 – 12% παγκόσμιου GNP 1995 – 30% παγκόσμιου GNP

4 Σύγχρονες Τάσεις Γεωγραφική διασπορά Βελτιωμένες μεταφορές Μείωση εμποδίων στο διεθνές εμπόριο Υποβάθμιση αστικών περιοχών Διεθνοποίηση παραγωγής Αναπτυσσόμενες αγορές Διαφοροποιήσεις κόστους εργασίας

5 N.A. Ασία Taiwan - εξάγει 70% της παραγωγής της - παράγει 20% των PCs παγκοσμίως Japan South Korea Taiwan Singapore Hong Kong China Μέγιστος ρυθμός ανάπτυξης εμπορίου

6 Β. Αμερική Mexico (1996): 2,000 νέα εργοστάσια 500,000 εργαζόμενοι Φθηνό εργατικό κόστος, χαμηλή παραγωγικότητα, ελλειμματικές υποδομές. USΑ: > 3,000 νέες χωροθετήσεις / χρόνο > 7,500 επεκτάσεις / χρόνο NAFTA (North American Free Trade Agreement) Canada-Mexico-United States

9 Διαχείριση σε παγκόσμια κλίμακα Επικοινωνία σε ξένες γλώσσες Διαφορετικά πρότυπα και έθιμα Διαχείριση ανθρώπινου δυναμικού Άγνωστη νομοθεσία και κανονιστικό πλαίσιο Απρόβλεπτα κόστη

10 Αποφασίζοντας για μια νέα επιχειρηματική μονάδα  Μεταβολή στη ζήτηση (θετική ή αρνητική).  Νέο προϊόν.  Αλλαγές στο οικονομικό περιβάλλον, π.χ. εργατικό κόστος, κόστος πρώτων υλών, πηγές πρώτων υλών, υποστηρικτικές επιχειρήσεις.  Κυβερνητικές ρυθμίσεις, π.χ. φορολογικοί νόμοι, αναπτυξιακά κίνητρα, περιβαλλοντικές ρυθμίσεις.

11 Ανταγωνιστικά Κριτήρια χωροθέτησης επιχειρήσεων Ανάγκη παραγωγής κοντά στην αγορά (ταχύτητα απόκρισης, διασυνοριακό εμπόριο, μεταφορικά κόστη) Ανάγκη παραγωγής κοντά στο κατάλληλο στελεχιακό δυναμικό (χαμηλό κόστος εργασίας, υψηλό επίπεδο εκπαίδευσης, επιχειρησιακή κουλτούρα)

12 Βασικά στάδια στην απόφαση για νέα χωροθέτηση 1. Συστηματική ανάλυση της ανάγκης για νέα χωροθέτηση. 2. Αναγνώριση των κρίσιμων παραγόντων για τον προσδιορισμό της θέσης. 3. Επιλογή γενικής γεωγραφικής θέσης. 4. Συγκεκριμένη επιλογή θέσης επιχείρησης.

13 Σ1: Ανάλυση της ανάγκης για νέα χωροθέτηση Μέγεθος Μονάδας Κόστος Κόστος Παραγωγής Κόστος Μεταφοράς Συνολικό Κόστος Ιδανικό Μέγεθος

14 Σ2: Κρίσιμοι παράγοντες προσδιορισμού θέσης Πρόσβαση στις αγορές και στους προμηθευτές Απόσταση από την κεντρική επιχείρηση Θέση ανταγωνιστών Κόστη παραγωγής και μεταφορών Αναπτυξιακά κίνητρα Περιβαλλοντικοί όροι Πρόσβαση στην τεχνολογία Εργασιακό κλίμα Ποιότητα ζωής Πολιτική σταθερότητα

15 - Κρίσιμοι Παράγοντες - Βιομηχανία  Απόσταση από την κεντρική επιχείρηση  Φορολογία, υποδομές, κόστος γής  Πρόσβαση στους προμηθευτές  Ευνοϊκό εργασιακό κλίμα  Πρόσβαση στις αγορές  Ποιότητα ζωής

16 - Κρίσιμοι Παράγοντες - Υπηρεσίες  Πρόσβαση στους πελάτες  Κόστος μεταφοράς  Θέση ανταγωνισμού  Site-specific Factors

17 Χωροθέτηση ανεξάρτητης μεμονωμένης μονάδας Επέκταση υπάρχουσας μονάδας Κατασκευή νέας μονάδας Μεταφορά μονάδας σε νέα θέση

18 Επέκταση υπάρχουσας μονάδας +Ενιαίο διοικητικό σχήμα +Μειωμένο κόστος κατασκευής +Μικρός χρόνος κατασκευής –Μικρότερη ευελιξία –Δυσκολότερη διαχείριση υλικών –Περισσότερο σύνθετη παραγωγή –Έλλειψη χώρου

19 Κατασκευή νέας μονάδας +Μικρότερος κίνδυνος απώλειας παραγωγής +Αποφυγή εργασιακών προβλημάτων +Εκσυγχρονισμός με νέα μηχανήματα +Μειωμένα μεταφορικά κόστη –Κόστος επένδυσης

20 Σ3: Επιλογή γενικής γεωγραφικής θέσης 1.Επιλογή παραγόντων απόφασης. 2.Διαμόρφωση λίστας εναλλακτικών περιοχών. 3.Συλλογή στατιστικών δεδομένων. 4.Συγκριτική ανάλυση με ενιαίο ποσοτικό δείκτη. 5.Εξειδίκευση ποσοτικού δείκτη.

88 Locating a facility in a Network Location of each facility in the network Allocation of work throughout the network Capacity may be affected by allocations Transportation Method

89 Locating a faclitiy within a network of facilities. Facilities may work independently (chain of restaurants) or interact (warehouses). Interaction between facilities requires solving of: - location - allocation (allocating work between facilities) - capacity (reallocationg of work affect the capacity)

90 Transportation Model 1.Create a row for each plant 2.Create a column for each warehouse 3.Create a single column for plant capacity 4.Create a single row for warehouse demand. 5.Split cells where plant and warehouse, rows and columns intersect 6.Place price per unit in half of each split cell 7.Place estimated capacities and demand figures for each plant and warehouse.

91 Transportation Model 8.Create a dummy warehouses if total capacity is greater than total demand. 8.1 Demand for the dummy warehouse should equal Total capacity – Total demand so as to raise total demand to equal total capacity. 8.2 Split the new intersection cells as in step 5 for dummy column 8.3 use a price of $ 0.00 per unit in the split cells 9.Create a dummy plant if total demand is greater than total capacity 9.1 Capacity for the dummy plant should equal Total demand – Total capacity so as to raise Total capacity to equal total demand 9.2 Split the new intersection cell as in step5 for the dummy row 9.3 Set the price per unit to the cost to the company for stock outs. If unknown or all stock out cost are equal allow price to be $0.00

92 Transportation Model 10. Solve model by placing the amount each plant should send each warehouse in the unused half of the split cells where 10.1 Total capacity of each plant is fully used 10.2 Total demand for each warehouse is fully met 10.3 Where total cost to met 10.1 and 10.2 is at a minimum.
